Question

Difficulty: MediumLarge Commercial Trucks and No-Zones

You are traveling on a multi-lane highway in the lane directly to the left of a large commercial tractor-trailer, positioned alongside the middle of its trailer. As traffic ahead slows, you realize you have been cruising in this position for several seconds. Which of the following is the safest driving practice to handle this situation?

  1. A
    Maintain your position directly alongside the truck's trailer until the traffic flow speeds back up.
  2. Adjust your speed to either fall back behind the truck or safely pass it to exit the truck's side No-Zone.Answer
  3. C
    Move closer to the left side of the truck's cab so the driver can spot your hood in their side window.
  4. D
    Honk your horn repeatedly to alert the truck driver that you are driving next to their vehicle.

Answer

Adjust your speed to either fall back behind the truck or safely pass it to exit the truck's side No-Zone.
Large commercial vehicles have significant blind spots along both sides, often called No-Zones. Staying alongside a truck's trailer keeps your vehicle hidden from the driver's view. The safest choice is to alter your speed by dropping back or safely finishing a pass to exit the blind spot quickly.

Step-by-Step Solution

1
Identify the hazard in the scenario
Recognize that driving alongside the trailer of a large commercial truck places your vehicle in a major side blind spot (No-Zone).
Large commercial trucks have extensive blind spots along both sides where passenger vehicles disappear from the truck driver's view.
2
Determine the proper defensive driving action
Change your speed relative to the truck by either slowing slightly to drop back behind it or safely accelerating to pass.
Exiting the blind spot restores a safe buffer zone and ensures your vehicle is visible in the truck driver's mirrors or windshield.
