A safety zone is a specially marked area for passengers to get on or off of buses or trolleys. You may not drive through a safety zone:

  1. When a bus or trolley is present.
  2. When a bus or trolley is unloading passengers.
  3. At any time for any reason. ✓

Answer: C. At any time for any reason.

You may not drive through a safety zone at any time for any reason.

Why this is the answer

The handbook describes safety zones as places reserved for people waiting for buses, streetcars, or trolleys, marked by raised buttons or markers on the road. It states the ban applies under every condition. That wording leaves no exception for whether a bus or trolley is there or whether riders are getting on or off. The nearby note about passing a stopped bus at no more than 10 mph does not make driving through the safety zone itself allowed.

Why the other answers are wrong

Remember it

Think of the raised markers as a fence around waiting riders: you never drive through that fence.
