Local signage restricts the use of engine brakes in a town you're driving through on a descent. What should you do?

Pick an answer

1. Stop using all forms of braking until you're past the restricted area
2. Ignore the restriction, since local signage cannot override federal highway rules on any road
3. Follow the restriction, relying more on your selected low gear and snub braking technique instead
4. Use the engine brake anyway if no one appears to be nearby
