Understanding Why Drivers Slow Down Next to 18-Wheelers

The phenomenon of drivers intentionally slowing down next to 18-wheelers has puzzled and angered many truckers for decades. This behavior poses significant risks and disrupts the smooth flow of traffic, leading to frustration and potential accidents.

Reasons for this Behavior

There are several reasons why some drivers might choose to slow down alongside large trucks. These include:

Lack of Lateral Distance Perception

Drivers who struggle with gauging lateral distances might find it easier to stay alongside a truck instead of passing it, assuming it will slow down naturally. This belief can lead to a dangerous situation where both vehicles are moving at a slow pace, causing a blockage in traffic flow.

Incorrect Speed Perception Due to Air Displacement

When a smaller vehicle passes a large truck, it often encounters air resistance or 'air wall' that can slow it down unexpectedly. If the driver's speed control mechanism (such as cruise control) is engaged, the vehicle might match the truck's speed unintentionally.

The Impact on Truck Drivers

Truck drivers face significant challenges when dealing with this behavior. When a slow-moving vehicle cuts in front of them, it can lead to abrupt braking, causing further delays and stress for all drivers in the vicinity.

Case Study: A Driver with Kids

A memorable incident occurred when a minivan, presumably with children on board, deliberately slowed down as it approached a large truck. Despite staying at a healthy speed uptil that point, the driver braked and matched the truck’s speed. This slow progress eventually led to a frustrating situation where the minivan resumed its high-speed journey, leaving the truck driver to endure the stress of prolonged slowdowns.

Hazards of "Hanging Out" Alongside Trucks

Driver behavior near 18-wheelers is not only disruptive but also potentially dangerous. Instances of tire blowouts while following or alongside trucks have been documented.

Case Study: Tire Blowout

One trucker recalls an incident on I-78 in Pennsylvania where a Toyota Prius closely followed a large truck. Despite the trucker’s efforts to provoke the driver to move, the latter remained attached. Soon, a loud sound (indicative of a retread tire coming loose) was heard, followed by a violent blowout. The debris was contained, and no damage was caused to the car. The driver of the Prius likely realized the dangers and avoided the trucker's large vehicle afterward.

Conclusion

Drivers need to be more aware of the potential hazards and safety risks associated with their behavior near 18-wheelers. Truckers often have to deal with slow-moving vehicles that disrupt their journey and cause inconvenience. It is crucial to acknowledge that these large vehicles belong on designated routes and should not be mixed with regular traffic.

Drivers are advised to pass trucks and maintain a safe distance. Failing to do so not only risks their own safety but also endangers others on the road.
