Difficulty: EasySpeed Limits and Speed Regulation

A driver is operating a slow-moving vehicle on a clear two-lane highway where the posted maximum speed limit is 55 mph55\text{ mph}. A queue of five or more trailing vehicles has accumulated directly behind the driver due to the slow speed, and passing is unsafe. Under standard speed regulation laws, what is the driver legally required to do?

  1. Pull safely off the roadway at a designated turnout or safe area to allow trailing traffic to pass.Answer
  2. B
    Maintain the current slow speed in the lane because driving below the maximum posted speed limit is always protected.
  3. C
    Increase speed to the posted maximum limit only if driving through an active school zone.
  4. D
    Speed up to 55 mph55\text{ mph} immediately, as drivers are always required to travel at the maximum posted limit.

Answer

The driver must pull off the roadway safely at a turnout or safe area to let accumulated traffic pass.
When traveling on a two-lane highway where passing is unsafe and a queue of five or more vehicles accumulates behind a slow vehicle, traffic regulation laws require the driver to pull off the road at a safe turnout area to let accumulated traffic pass safely.

Step-by-Step Solution

1
Identify the traffic flow situation
A slow-moving vehicle is impeding a line of five or more trailing vehicles on a two-lane road where passing is unsafe.
Traffic laws regulate minimum speed and flow to prevent dangerous queuing and tailgating.
2
Apply slow-moving vehicle turnout regulations
The driver must yield the roadway by pulling into a designated turnout or safe location to allow trailing vehicles to pass.
Holding up traffic queues leads to reckless passing attempts and severe head-on collision risks.
