Which signal indicates all vehicles must stop?

Which signal indicates all vehicles must stop?

• A. palm forwards facing windscreen
• B. stick upright with other arm out
• C. End of 20 mph zone
• D. hand to the left

Answer: (B)

When an authorised person such as a police officer or traffic marshal needs all vehicles to stop, they use a baton held upright with one arm extended. The raised baton is highly visible and clearly communicates the instruction to stop to every driver, regardless of direction. The other signals listed don’t convey this universal instruction: turning left, ending a speed limit zone, or a generic hand gesture to the left all have different, more limited meanings.
