Arkansas Driving Permit Practice Test

When tractor-trailers make a right turn, what do they often need to do?

1. Swing left

2. Swing right

3. Stop

4. Reverse

The correct answer is: Swing left

When tractor-trailers make a right turn, they often need to swing left. This maneuver is necessary to ensure that the rear end of the trailer clears the corner without hitting the curb or any obstacles. By swinging left before making a right turn, the driver can create enough space for the trailer to follow the path of the turn safely. This technique is commonly known as a "button hook" or a "jackknife" maneuver. It is essential for other drivers to be aware of this behavior of tractor-trailers to avoid accidents and maintain safe distances when sharing the road with these large vehicles. Option B (Swing right) is incorrect because swinging right before making a right turn would increase the risk of the trailer hitting the curb or other vehicles on the right side of the road. Option C (Stop) is not typically necessary unless traffic conditions require it, and stopping abruptly during a turn can be dangerous. Option D (Reverse) is not a standard practice for tractor-trailers making right turns and should be avoided to prevent accidents and traffic congestion.
