Knowing the Standard Hand Signals Used in Driving
Last reviewed: 2026 · Driviology Road Safety Education Team
Quick Answer
Standard hand signals - a straight arm out for a left turn, an upward-bent arm for a right turn, and a downward-bent arm for stopping - remain a valid backup for communicating intentions when a vehicle's electronic signals fail.
Though electronic turn signals are standard on modern vehicles, hand signals remain a valid and occasionally necessary backup.
The Standard Signals
- Left arm straight out - left turn
- Left arm bent upward - right turn
- Left arm bent downward - stopping or slowing
When They Are Still Necessary
If your vehicle's direction indicators fail, hand signals let you continue communicating your intentions safely until the issue is fixed.
Cyclists Rely on Them Regularly
Unlike most vehicles, many cyclists rely on hand signals as their primary way of indicating turns, so recognizing these signals matters for drivers sharing the road with them.
