Jeffrey P. Gale, P.A. // The Science of Looming Motion and Looming Threshold in Rear-End Motor Vehicle Collisions

Jeffrey P. Gale, P.A. — Fri, 19 Dec 2025 18:56:18 GMT

Rear-end collisions account for more than 25 percent of all roadway motor vehicle accidents. The reflexive response is to blame the driver of the approaching vehicle – the one who strikes the vehicle ahead. Florida law reinforces this instinct by creating a rebuttable presumption of fault against the trailing driver. Gulle v. Boggs, 174 So. 2d 26, 27–29 (Fla. 1965) (When “a defendant runs into the rear of a plaintiff’s automobile while the plaintiff is stopped for a traffic light or at an intersection, there is a presumption of negligence of the defendant … . The presumption provides a prima facie case which shifts to the defendant the burden to go forward with the evidence to contradict or rebut the fact presumed. When the defendant produces evidence which fairly and reasonably tends to show that the real fact is not as presumed, then the impact of ‘the presumption is dissipated.’ Whether the ultimate fact has been established must then be decided by the jury from all the evidence before it without the aid of the presumption.”)

That presumption, however, is not absolute. Law enforcement, courts, and personal injury practitioners should resist the temptation to stop their analysis there. Attentive, reasonable drivers can – and sometimes do – collide with the rear of a leading or stationary vehicle in broad daylight through no fault of their own.

Our firm, together with Attorney Sean Domnick, represented a client in litigation against a motor coach company and its driver arising from precisely such a scenario. Our client was operating his employer’s passenger bus when he struck the rear of a motor coach stopped in a through lane of travel. There was no traffic condition requiring the stop. The motor coach was not disabled; it had not run out of fuel, suffered a mechanical failure, or experienced any emergency. Nevertheless, it remained stationary in a live traffic lane.

Our client approached from behind in the same lane with an unobstructed view beginning approximately 2,500 feet away. There were no vehicles in front of or beside him in any lane. He observed the motor coach at a distance, but did not perceive that it was stopped until he was too close to avoid a collision. The result was catastrophic injuries. (Our client was extricated from his vehicle using the Jaws of Life and airlifted to the hospital.)

We retained multiple experts to address discrete aspects of the case. An engineer testified regarding speeds, distances, and stopping calculations. A trucking expert addressed industry standards and safety practices. Medical experts explained the severity and permanence of our client’s injuries, and an economist quantified past and future economic losses. None of those experts, however, was qualified to explain why a reasonably attentive driver can collide with a stationary vehicle without being negligent.

That explanation lies within the domain of human factors science.

We retained a leading human factors expert to address this critical question. Rather than attempting a technical exposition here, I will briefly describe – at a lay level – the most significant principles at issue: “looming motion and looming threshold.”

In roadway safety, looming motion concerns the human ability to perceive whether an object ahead is moving or stationary. Counterintuitively, a stopped vehicle in the roadway can be among the most difficult hazards to detect, even in broad daylight. At long distances, a stationary vehicle can produce visual information indistinguishable from that of a moving vehicle traveling at the same speed as the observer. In such circumstances, the absence of angular expansion delays recognition that the object ahead represents a hazard. Absent strong visual cues – such as warning triangles, visible occupants outside the vehicle, or signs of roadside activity – the human visual system may not immediately register that a vehicle ahead is not moving.

Closely related is the role of expectation. Human perception is influenced by what a driver reasonably anticipates encountering. Expectation can delay the recognition of danger. In our case, the collision occurred on our client’s regular route, one he had driven daily for more than ten years. The location – near the entrance to a major theme park – was specifically designed to allow commercial passenger vehicles to approach without interruption or delay. In all those years, our client had never encountered a vehicle stopped in this portion of the roadway without an apparent reason.

His reasonable expectation was that traffic would continue flowing smoothly toward the entrance gate located 800 to 1,000 feet ahead. Accordingly, although he saw the motor coach, he did not perceive that it was stationary. The combination of diminished perceptual cues and reasonable expectation created the perfect storm. While the motor coach driver had multiple safe alternatives and made an affirmative choice to stop in a through lane, our client – due to a scientifically explainable failure of perception – was deprived of any meaningful opportunity for cognitive choice.

The concept of “looming distance” is well established in human factors research. Mathematical models can determine the distance at which a stationary hazard should become perceptible to a reasonably attentive driver. Predictably, litigation focuses on the variables—such as vehicle speed—to be used in those calculations. In this case, however, both sides’ engineers agree on the speed at impact.

The “looming threshold” is the point at which the rate of angular expansion becomes sufficient for the human visual system to register that an object ahead is stationary or closing rapidly. This threshold is not subjective guesswork; it is a measurable and well-studied phenomenon grounded in vision science.

The looming threshold occurs later—often dramatically later—when:

The stopped vehicle presents a large, uniform profile (e.g., a bus or motor coach);
There are no visual cues indicating distress or abnormality;
The roadway geometry and traffic flow create an expectation of uninterrupted movement; and
Lighting and contrast conditions do not emphasize depth or closure.

Until the looming threshold is crossed, a driver may see the vehicle without perceiving it as a hazard.

Our human factors expert opined – using established science – that by the time a reasonably attentive driver would have perceived the motor coach as stopped, there was insufficient time or distance to avoid the collision. Importantly, all evidence supported that our client was, in fact, attentive.

It also bears emphasis that perception and reaction are not synonymous. Even after a hazard is perceived, additional time is required for cognitive processing and physical response.

This discussion is not intended to suggest that trailing drivers are never at fault. Clearly, many rear-end collisions result from inattention or negligence. The takeaway is more modest, but critical: lawyers must be willing to look beyond presumptions and examine the science. When they do, the results can be both professionally rewarding and profoundly meaningful to the client.

The case was tried before an Orlando jury, which awarded nearly $2,000,000 in damages and apportioned fault almost equally between our client and the corporate owner of the stopped motor coach.

Jeffrey P. Gale, P.A. /// Disabled Commercial Vehicles Are Serious Roadway Hazards

Jeffrey P. Gale, P.A. — Tue, 18 Nov 2025 23:09:18 GMT

Disabled commercial vehicles pose significant hazards to motorists.

Although approaching drivers often bear much of the blame for rear-end collisions, commercial vehicles that become disabled in active lanes of traffic frequently contribute to serious and fatal accidents—often through little or no fault of the approaching motorist. These crashes occur not only at night or in foggy conditions, or on curved roadways, but surprisingly often in broad daylight on straight, unobstructed highways.

To reduce these dangers, the U.S. Department of Transportation’s Federal Motor Carrier Safety Administration has established detailed regulations governing disabled commercial vehicles. For commercial motor vehicles—buses and trucks with a gross vehicle weight rating (GVWR) over 10,000 pounds (U.S. DOT Rule 571.125 S3) – that stop on the traveled portion of a highway for any reason other than normal traffic, 49 CFR 392.22 requires the following:

Activation of Hazard Warning Flashers.
The driver must immediately activate the vehicle’s hazard-warning flashers and keep them activated until the required warning devices are placed. According to Rule 393.5, hazard warning signals are lamps that flash simultaneously on all sides of the commercial vehicle to alert approaching drivers. Rule 393.19 further requires that these flashers operate independently of the ignition switch.

Placement of Warning Devices.
As soon as possible, and in all cases within 10 minutes, the driver must place the prescribed warning devices in the locations specified by Rule 392.22(b)(1)(i–iii), (b)(2), (b)(2)(iv), and (b)(2)(v). The required devices—three bidirectional emergency reflective triangles, at least six fusees, or three liquid-burning flares—are identified in Rule 393.95. As noted in Section 571.125 S2, the purpose of these standardized devices is “to reduce deaths and injuries due to rear-end collisions between moving traffic and disabled vehicles.”

These requirements apply with only minor variation between daytime and nighttime conditions.

The regulations underscore the critical importance of preparedness. Rule 392.8 states that no commercial motor vehicle may be operated unless the driver is satisfied that the required emergency equipment is present and ready for immediate use.

The purpose of this discussion is to highlight a counter-intuitive but important concept: disabled vehicles can create dangerous conditions that contribute to major accidents even when approaching drivers are exercising appropriate care. Because many of these incidents result in severe injuries or fatalities, fault should not be automatically attributed to the following motorist. A thorough investigation of the specific circumstances of each collision is essential.

Jeffrey P. Gale, P.A. // Understanding Florida’s Rear-End Collision Presumption

Jeffrey P. Gale, P.A. — Wed, 11 Jun 2025 14:56:33 GMT

In 1958, Florida joined a small number of states in adopting a legal presumption of negligence against trailing drivers involved in rear-end motor vehicle collisions. This shift was established in McNulty v. Cusack, 104 So.2d 785 (Fla. 2d DCA 1958), and later endorsed by the Florida Supreme Court in Bellere v. Madsen, 114 So.2d 619 (Fla. 1959).

The Legal Rationale

The presumption is rooted in practical evidentiary concerns. Typically, plaintiffs bear the burden of proving all four elements of negligence: duty, breach, causation, and damages. But in rear-end crashes, plaintiffs often know they were hit from behind but have no access to the circumstances leading up to the impact—leaving gaps in proof for breach and causation.

To address this, Florida courts created a rebuttable presumption: if a rear-end collision occurs, the trailing driver is presumed negligent. This shifts the burden of production to the defendant, who must offer a “substantial and reasonable explanation” to overcome the presumption. If successful, the case proceeds to the jury without the benefit of the presumption. See Gulle v. Boggs, 174 So.2d 26, 28–29 (Fla. 1965); Brethauer v. Brassell, 347 So.2d 656 (Fla. 4th DCA 1977).

Originally developed during Florida’s contributory negligence era—where any negligence on the plaintiff’s part barred recovery—the rule had significant weight. Under today’s comparative fault framework, however, negligence is apportioned, and partial fault does not automatically defeat a claim. See Shayne v. Saunders, 176 So. 495 (Fla. 1937); Stephens v. Dichtenmueller, 207 So.2d 718 (Fla. 4th DCA 1968), quashed on other grounds.

Modern Interpretation: Birge v. Charron

In Birge v. Charron, 107 So.3d 350 (Fla. 2012), the Florida Supreme Court clarified that the rear-end presumption is “an evidentiary tool” designed to bridge gaps in liability and causation when evidence is one-sided. Importantly, it is not absolute.

Where there is evidence that the front driver may have been negligent, the presumption is rebutted. At that point, the case must go to a jury for resolution—without the presumption. It may remain only as a permissible inference the jury is free to accept or reject. This standard was reaffirmed in Crime v. Looney, 328 So.3d 1157 (Fla. 1st DCA 2021).

Real-World Application: A Case Study

We recently handled a case involving a catastrophic, multi-vehicle crash on Florida’s Turnpike. Our client was sideswiped by an SUV that had been rear-ended, causing their vehicle to be propelled into a tree at high speed. The chain-reaction began with a rear-end collision—clearly placing the trailing vehicle at the center of the causation analysis.

We argued that the presumption of negligence should apply to the vehicle that initiated the sequence. However, the court noted that the rear-ended SUV had come to a sudden stop on a section of highway where such stops are not expected, unlike urban roads with frequent stops for businesses or intersections.

Because there was a factual dispute over whether the front vehicle’s conduct contributed to the crash, the court ruled that the presumption did not apply. The case ultimately settled for a confidential amount.

Key Takeaways

Presumption of Negligence: In Florida, a rear-end collision creates a presumption that the trailing driver was negligent.
Rebuttable Standard: The presumption can be rebutted by presenting a reasonable explanation (e.g., sudden, unexpected stop by the lead vehicle).
Comparative Fault: Even if the lead driver was partially at fault, liability can be shared rather than barred entirely.
Not Always Applicable: The presumption is less likely to apply on highways or areas where sudden stops are unusual.

This rule continues to play a vital role in rear-end crash litigation, especially where direct evidence is hard to come by. But as our case illustrates, it is not a one-size-fits-all solution.

Jeffrey P. Gale, P.A. // Republicans Push Sovereign Immunity for Private Companies

Jeffrey P. Gale, P.A. — Mon, 22 Apr 2024 18:12:22 GMT

This blog is the second on recent efforts by Republican legislators with the consequence of making Florida’s roads and highways more dangerous. (The first blog: Jeffrey P. Gale, P.A. // Republican Legislators Work to Make Florida’s Roadways Less Safe.)

Section 768.28(5)(a), Florida Statutes limits the recovery against the state and its agencies and subdivisions for tort lawsuits to $200,000 per individual claim and $300,000 total for all claims arising out of the same incident or occurrence.

No matter how catastrophic and life-altering the injuries may be or whether death results from the negligence of the sovereign, this is the hard cap. It does not matter what a judge or jury decides regarding the extent of the damages.

Section 768.28(5)(a) is the outgrowth of section 768.28(1), which is a limited waiver by the state of the doctrine commonly referred to as “Sovereign Immunity.” The doctrine is derived from English common law under which the King could not be sued on the theories that he could do no wrong, and that there could be no legal rights against the authority that makes the laws upon which the rights depend. See Miles McCann, Visiting Fellow, National Association of Attorneys General, State Sovereign Immunity, Nov. 11, 2017, https://www.naag.org/attorney-general-journal/state-sovereign-immunity/(last visited Jan. 23, 2024).

In Alden v. Maine, 527 U.S. 706, 728 (1999), the Supreme Court of the United States held that the doctrine was adopted by our country’s Founders in the Constitution itself rather than the Eleventh Amendment, solidifying its place in American jurisprudence. The doctrine is available to the federal government and every state.

Not every state chooses to hide behind sovereign immunity. California and New York, states with large populations and high costs of living and medical care like Florida, have no caps on suits against their state and local governments. Among the states using cap limits, Florida’s numbers are some of the lowest, making them a mere slap on the wrist to wrongdoers and failing to encourage safer practices and procedures.

The Florida Department of Transporation (FDOT) enters into contracts with private companies on many of its projects. The contracts require a degree of vetting to determine competence and allow for oversight by the sovereign. 768.25(5) extends the sovereign caps to these companies while performing under FDOT contracts, providing a measure of insulation not otherwise available to them on private projects. So, for example, the negligence of one of these companies on a private project resulting in catastrophic injuries could lead to a final judgment against the company for millions of dollars, whereas the same facts on a sovereign project would be limited to a $200,000 (per person) final judgment.

For two months every year, Florida’s senators and representatives meet in Tallahassee to create new laws. This year, bills were offered to extend the sovereign caps to companies that were not in privity of contract with the governmental entities. As such, they would not be vetted for competence by the sovereign or be subject to the sovereign’s scrutiny.

This is a recipe for an increase in dangerous conditions. Under no circumstances would the arrangement promote safety.

Thankfully, due to the hard work of the staff and members of the Florida Justice Association (FJA), the worst aspects of the proposed bills were eliminated or watered down.

All of the dangerous bills were proposed by Republicans.

Elections matter.

Jeffrey P. Gale, P.A. // Republican Legislators Work to Make Florida’s Roadways Less Safe

Jeffrey P. Gale, P.A. — Tue, 16 Apr 2024 17:53:01 GMT

“Sine die,” the dropping of the handkerchief ceremony to signal the end of the legislative session in Florida, could not come soon enough this year for residents hoping for safer roads and highways.

During the 2024 legislative session, which ran from January 9, 2024 to March 8, 2024, Republican legislators proposed a variety of bills that would insulate trucking companies, road contractors, engineers and other contractors from liability when they make Florida’s roadways more dangerous.

Commercial Vehicles Penske Corporation, Inc., one of the largest trucking rental companies in the nation, backed legislation that would give vehicle owners, lessors, and operators immunity from liability when those vehicles were not equipped to meet industry safety standards. Florida is not the only state targeted for similar legislation.

Industry safety standards are developed from the practice of customary methods and conduct over time. In many instances, the standards are codified in statutes, regulations, and industry publications, while experts in various fields often testify based on their experience and knowledge. Evidence of violation of industry standards is admissible as non-conclusive evidence of negligence. St. Louis-San Francisco Railway Company v. White, 369 So.2d 1007 (Fla. 1st DCA 1979). See also: St. Louis-San Francisco Railway Company v. Burlison, 262 So.2d 280 (Fla. 1st DCA 1972); Clements v. Boca Aviation, Inc., 444 So.2d 597 (Fla. 4th DCA 1984); Nance v. Winn Dixie Stores, Inc., 436 So.2d 1075 (Fla. 3rd DCA 1983); Reese v. Seaboard Coast Line Railroad Company, 360 So.2d 27 (Fla. 4th DCA 1978).

Sen. Travis Hutson (Palm Coast) and Rep. Randy Maggard (Dade City) sponsored bills lowering the safety standards commercial vehicle owners, lessors, and operators must meet to the requirements of Federal Motor Vehicle Safety Standards (49 CFR 571) — which is only a portion of the federal regulations dealing with motor vehicles and does not include many of the safety standards that have become common industry practice. Under the proposed legislation, Penske and others would be immune from liability by showing mere compliance with 49 CFR 571, despite ignoring a wealth of tried and proven industry standards developed over millions of roadway miles.

Examples of things the bill would allow include:

A trucking company could remove or disable the forward collision warning systems that come standard in trucks, raising the risk of rear-end collisions.
Ignoring safety recalls.

Thankfully, through the efforts of the staff and members of the Florida Justice Association, the bill died.

Unfortunately, like zombies rising from the grave, these bad actors will be back. The war never ends.
