You should signal to turn ____ before beginning the turn.

  1. 100 feet ✓
  2. 50 feet
  3. 20 feet
  4. 10 feet

Answer: A. 100 feet

You should signal at least 100 feet before beginning the turn.

Why this is the answer

The Texas handbook gives a specific distance: put on your turn signal at least 100 feet before you turn. It also says to signal continuously for that distance before turning or stopping and to signal early enough for others to see and understand your intention. The other choices are all shorter than the handbook's minimum, so they do not meet the rule.

Why the other answers are wrong

Remember it

Pair the turn signal with slowing down; the handbook puts both at the same 100-foot mark.
