California Driver License (DMV) Written Practice Test

A white rectangular sign with black lettering typically indicates regulatory information or instruction. This type of sign is used to give drivers specific instructions or regulations to follow on the road. This is different from a construction zone, which is usually marked by orange signs, and advisory or warning signs, which provide drivers with additional information about the road ahead. Destination or direction information is usually displayed on green or blue signs. Therefore, these options can be ruled out.
