What should drivers do when they see a yellow sign?

When drivers see a yellow sign, they should prepare to potentially change their driving behavior. Yellow signs are typically used to indicate caution and alert drivers to upcoming changes in road conditions, hazards, or potential hazards in the roadway. These can include warning of curves, intersections, or pedestrian crossings.

The intention behind a yellow sign is not to instruct drivers to stop or ignore the sign, but rather to prepare them for something they may need to respond to by adjusting their speed or being more vigilant. Drivers should interpret these signs as a signal to be alert and ready to react according to the situation ahead. This proactive approach is essential for ensuring safety on the road, as it can help prevent accidents.
