Difficulty: MediumSharing the Road with Large Vehicles

When a large commercial truck signals a right turn and swings left into an adjacent lane, it is safe for a trailing vehicle to pass the truck on its right side.

Answer: Answer

Answer

False
The statement is false because large commercial trucks must swing wide to the left to complete a right turn. Passing on the right during this maneuver exposes vehicles to the truck's blind spot and the path of the off-tracking rear wheels, causing a severe right-turn squeeze collision.

Step-by-Step Solution

1
Analyze truck turning mechanics and off-tracking
Large combination vehicles experience off-tracking, where the rear wheels follow a shorter path than the front wheels during a turn.
Truck drivers must maneuver the tractor wide to the left to ensure the trailer clears the curb or street corner.
2
Evaluate the risk of entering the right lane gap
Entering the open space created on the right side of a turning truck positions the vehicle in the truck's blind spot and in the direct path of the closing trailer.
The driver of the truck cannot see vehicles on the inside of the turn, leading to a right-turn squeeze accident.
