What signal indicates a desire to go straight on in traffic?

The signal that indicates a desire to go straight on in traffic is achieved by extending the left arm horizontally out to the side. Waving the right arm is typically not a recognized standard signal for indicating straight travel.

In the context of traffic hand signals, drivers mean to communicate their intentions to other road users. The traditional signals are designed to be clear and easy to understand. The left arm extended indicates that the driver intends to maintain their current direction, which is straight.

It’s important for drivers, pedestrians, and cyclists to understand and recognize these signals to ensure safety and clarity on the road. Proper signaling helps to prevent accidents and misinterpretations in heavy or complex traffic situations.

Understanding the correct way to signal when going straight is part of the broader knowledge necessary for effective emergency response driving, where clear communication can significantly impact safety during critical situations.
