CDL · Passenger vehicles
A sign shows a speed for an upcoming curve. What does that posted speed represent?
Correct answer: A speed at which passenger cars can travel safely in normal weather.
Answer options
- AA speed at which both cars and buses can travel safely in bad weather
- BA speed at which passenger cars can travel safely in normal weather Correct
- CA speed at which buses can travel safely in normal weather
Why
The speed posted for a curve is set with cars and good weather in mind, so it may be too high for many buses even when the road is dry. Taking a curve too fast can make a bus roll over when traction is good or slide off the road when traction is poor.
