Can Self-Driving Trucks Reduce the Risk of Accidents?

As autonomous vehicle technology rapidly advances with new self-driving capabilities, the trucking sector and automotive safety regulators envision automation as a pathway towards improving public safety by potentially reducing truck accident rates.

While self-driving trucks aren’t currently deployed outside controlled pilots and testing programs, widespread adoption may be on the horizon.

But can robotic truckers truly outperform human truck drivers when it comes to avoiding crashes, injuries, and loss of life?

The trucking industry is vital to the national economy, with over 70% of all freight tonnage in the United States transported by commercial trucks and tractor-trailers traversing the nation’s highways.

However, with over 4 million miles traveled daily by these heavy, high-profile vehicles, accidents involving trucks remain an ever-present danger for other motorists sharing the roads.

According to the National Highway Traffic Safety Administration (NHTSA), large trucks account for around 10% of all vehicles involved in fatal crashes annually, despite being only 4% of vehicles on the roadways.

Sadly, the majority of deaths in truck accidents are passenger vehicle occupants due to the immense forces these massive vehicles generate upon impact.

Most of these truck accidents are caused by human error, or negligence.

The Promise of Crash Prevention

Developers of autonomous trucking systems tout their technologies as having the capability to dramatically lower risks of the types of accidents most commonly caused by human errors, which account for over 90% of truck collisions annually.

By leveraging self-driving tech, some of the biggest contributors to truck crashes could potentially be rendered obsolete.

Fatigue and Inattention

Driver fatigue and distraction/inattention are factors in over 40% of all large truck crashes, according to FMCSA data.

With no human operators, self-driving trucks have zero risk of driver alertness issues. On-board safety systems seamlessly monitor all road conditions without lapses or distractions.

Impaired Operation

Roughly 3% of truck drivers involved in fatal crashes have blood alcohol levels over the legal limit. Autonomous trucks can’t drive drunk or have judgment impaired by drugs, prescriptions, health conditions, or other forms of impairment.

Speeding and Aggressive Driving

Around 23% of truck crashes happen with at least one driver operating too fast for conditions or exhibiting road rage behaviors. Self-driving trucks are programmed to rigidly obey all speed limits and traffic laws while practicing defensive driving strategies.

Poor Directional Control

Almost 10% of truck crashes result from improper maneuvers like unsafe lane changes, turns, or backing procedures. Self-driving systems are designed to properly execute all directional movements through intelligent path planning algorithms.

Environmental Factors

Inclement weather, low visibility, roadway obstacles, and slippery road surfaces all contribute heavily towards truck accident risks when encountering rapidly changing environmental conditions.

Autonomous systems fuse multiple sensor types to immediately detect and adjust for all potential hazards.

Lack of Driver Experience

New truck drivers pose particularly high risks, with the first year behind the wheel having twice the likelihood of getting into a crash compared to longer-tenured drivers. Autonomous systems don’t experience learning curves or lack situational experience.

Besides preventing the types of crashes most commonly caused by human shortcomings like fatigue, impairment, and poor judgment, autonomous trucks promise additional transformative safety benefits.

Self-driving capabilities like precision braking and steering enable optimized safe following distances and high-precision driving maneuvers that push the limits of accident avoidance through advanced physics models.

Highway autopilot systems leverage smart routing and logistics data to calculate the safest routes and times while orchestrating truck platooning capabilities to pack groups of trucks together in super-aerodynamic convoys with shorter following gaps.

Shorter travel distances and timing patterns avoiding rush hours could potentially reduce overall accident exposure as well.

Early iterations of autonomous trucking systems are already showcasing promising potential for crash prevention when compared to conventional human-controlled operations.

Obstacles and Considerations

While the technological possibilities for self-driving truck crash prevention are exciting, substantial hurdles exist before achieving widespread autonomous deployment and regulatory acceptance.

Substantial questions remain surrounding self-driving system reliability, performance, redundancies, validation, and oversight.

Primary among concerns are edge case conundrums that push autonomous driving technologies to their limits – events like encountering construction zones, debris, accidents already in progress, illegal traffic behaviors, and other chaotic conditions not yet capably handled by machine systems alone.

There are also significant legal and liability uncertainties remaining around standards for self-driving truck oversight, responsibilities over human monitors/attendants, and requirements for human interventions.

Ethical debates around accident avoidance scenarios and decision “rationales” utilized by autonomous systems continue to make regulators uneasy about ceding all controls to robots.

On top of technology and legal issues, there are obstacles around trucker workforce transitioning, infrastructure retrofitting, security from cyber threats, and challenges convincing the general public to embrace driverless trucks.

Consumer surveys consistently voice lack of confidence about sharing roads with 40-ton vehicles having no human in control.

The Road Ahead

Automotive safety experts and accident analysts agree that self-driving trucks certainly have immense potential for mitigating crashes caused by human shortcomings and errors.

However, the path towards full, widespread automation remains full of complex hurdles and pitfalls to navigate.

A prudent approach focuses on adopting self-driving systems in measured incremental phases, allowing regulations and infrastructure to gradually adapt.

Starting with geo-fenced highway autopilot duties on interstate routes and segregating autonomous movements to truck-only corridors can build public confidence before graduating to trickier city routes.

If executed thoughtfully and centered on data-driven safety enhancements over profit motivations, self-driving trucks have the ability to reshape public safety paradigms for the heavily-traveled freight highway system.

But it will take immense coordination between government, tech developers, truck operators, infrastructure overseers, and the public to ensure autonomous trucking truly manifests as the safer revolution it promises.
