Washington Written Drivers Permit Practice Test

On a highway with three lanes in each direction, a vehicle towing a trailer keeps to the right because

1. It moves faster than other vehicles

2. It moves slower than other vehicles

3. It has the right of way

4. It is easier to exit from the right lane

The correct answer is: It moves slower than other vehicles

On a highway with multiple lanes in each direction, a vehicle towing a trailer will typically keep to the right because it moves slower than other vehicles. This is important for safety reasons as vehicles towing trailers generally have a slower acceleration and deceleration rate compared to regular passenger vehicles. By staying in the right lane, the driver allows other vehicles to pass more easily on the left lanes without causing traffic congestion or potential hazards. This practice helps maintain a smoother flow of traffic and reduces the likelihood of accidents or unsafe maneuvers caused by slower-moving vehicles in faster lanes. The other options are not correct: A. It moves faster than other vehicles - This is not the case, as vehicles towing trailers usually travel at a slower speed compared to other vehicles. C. It has the right of way - The right of way is determined by traffic laws and road signs, not by the fact that a vehicle is towing a trailer. D. It is easier to exit from the right lane - While it might be easier to exit from the right lane on some occasions, the main reason for a vehicle towing a trailer to stay in the right lane is because it moves slower than other vehicles.
