In 50-55 mph traffic you are least likely to have an accident if you:

Answer: D — Stay within that speed range

In 50-55 mph traffic, staying within that speed range is the least likely scenario to result in an accident. Driving at a speed consistent with the flow of traffic promotes uniform traffic movement and reduces the likelihood of sudden maneuvers or unexpected speed differentials among vehicles. This choice is the most suitable option for ensuring safety and reducing the probability of accidents on the road. The other options either advocate for driving at speeds that disrupt the flow of traffic (A and C) or driving at an unusually slow speed that may cause congestion or unsafe lane changes (B). Driving too fast or too slow in comparison to other vehicles increases the risk of accidents by creating hazardous conditions. Therefore, staying within the 50-55 mph speed range is the safest choice in this scenario.
