Question

Difficulty: HardRegulatory Signs

Under standard traffic regulations, a rectangular white regulatory sign displaying the message 'SLOWER TRAFFIC KEEP RIGHT' permits a motorist traveling at the maximum posted speed limit to continuously occupy the far-left lane, even when faster traffic approaches from behind.

Answer: Answer

Answer

False. Motorists traveling slower than the surrounding traffic flow must yield the left lane and move to the right, regardless of whether they are driving at the maximum posted speed limit.
The statement is false. Rectangular regulatory signs reading 'SLOWER TRAFFIC KEEP RIGHT' mandate that drivers moving slower than the general flow of traffic must move out of the left passing lane. Obeying the maximum speed limit does not grant permission to block the left lane when trailing vehicles approach, as maintaining smooth traffic flow and preventing left-lane queueing are regulatory requirements.

Step-by-Step Solution

1
Identify the legal classification and mandate of the 'SLOWER TRAFFIC KEEP RIGHT' sign.
Recognize it as a white rectangular regulatory sign that enforces lane allocation rules.
Regulatory signs inform road users of traffic laws and regulations that must be obeyed.
2
Analyze how speed limit compliance interacts with lane allocation rules.
Determine that traveling at the posted speed limit does not override the requirement to keep right when obstructing faster traffic.
Left lanes on multi-lane highways are designated primarily for passing, and impeding traffic flow creates safety hazards.
3
Evaluate the truth value of the statement.
The statement is false because the regulatory sign obligates slower vehicles to vacate the left lane.
The regulatory mandate focuses on relative traffic speed rather than absolute speed limit compliance.
