Texas Driver's License Knowledge TestTraffic Signs and SignalsMedium
A motorist is driving on a multi-lane highway and observes a rectangular white sign with the words 'SLOWER TRAFFIC KEEP RIGHT' posted above the rightmost lane. What does this sign indicate?
- AThe right lane is about to end, and drivers should prepare to merge.
- BThe right lane is designated for commercial trucks only.
- CAll vehicles must merge left at the next intersection.
- DVehicles traveling below the normal speed of traffic should use the right lane.
Show answer & explanationAnswer & explanation
Correct answer: D. Vehicles traveling below the normal speed of traffic should use the right lane.
The 'SLOWER TRAFFIC KEEP RIGHT' sign is a regulatory sign that instructs drivers of vehicles traveling slower than the general flow of traffic to use the right-hand lane. This promotes smoother traffic flow and reduces congestion.
Why the other options are wrong
- A. A 'Right Lane Ends' or similar warning sign would indicate an impending merge, not this regulatory sign.
- B. This sign does not designate lanes for specific vehicle types like trucks.
- C. The sign indicates lane usage based on speed, not a mandatory merge.
