Difficulty: MediumRegulatory Signs

A motorist driving along a rural two-lane highway approaches a white rectangular regulatory sign reading 'DO NOT PASS'. Ahead of the motorist is a slow-moving tractor traveling well below the posted speed limit. Which action is legally required of the driver in this situation?

  1. Remain in the current lane behind the slow-moving vehicle until reaching a roadway segment where passing is legally permitted.Answer
  2. B
    Overtake the slow-moving vehicle immediately if the opposing lane is visibly clear of oncoming traffic for at least 500 feet.
  3. C
    Treat the sign as an advisory notice and execute the pass at a reduced speed while activating hazard lights.
  4. D
    Flash high-beam headlights to instruct the slow-moving vehicle to yield right-of-way and bring your vehicle to a complete stop on the shoulder.

Answer

The driver must remain in their current lane behind the slow-moving vehicle until reaching a zone where passing is legally permitted.
White rectangular signs with black lettering are regulatory signs that convey mandatory laws. A 'DO NOT PASS' sign strictly prohibits drivers from crossing the centerline to overtake another vehicle under any circumstance until entering a section of roadway where passing is allowed.

Step-by-Step Solution

1
Identify the classification and meaning of the traffic sign.
A white rectangular sign reading 'DO NOT PASS' is a regulatory sign that issues an absolute legal prohibition against passing other vehicles.
Regulatory signs inform road users of traffic laws and regulations that must be obeyed at all times.
2
Evaluate the traffic situation against the regulatory sign requirement.
Even though a slow-moving tractor is ahead, the regulatory prohibition applies without exception for slow traffic.
Drivers may not cross into the opposing lane to pass in a marked no-passing zone regardless of the lead vehicle's speed.
3
Determine the proper driver response.
Maintain a safe following distance behind the slow vehicle and wait until passing is legally allowed.
Compliance with regulatory signs ensures safety and avoids moving violations.
