What do all regulatory devices on the road instruct you to do?

All regulatory devices on the road, such as traffic signs and signals, are designed to guide drivers in how to operate their vehicles safely and legally. These devices communicate specific rules of the road, such as when to stop, which direction to proceed, and what speed limits to adhere to.

For example, a stop sign instructs drivers to come to a complete stop before proceeding, ensuring that they yield the right of way to other vehicles and pedestrians. Similarly, speed limit signs inform drivers of the maximum speed allowed on a particular road segment, promoting safe driving practices and reducing the risk of accidents.

The role of regulatory devices is to maintain order on the roads, enhance safety for all users, and facilitate smoother traffic flow. This is why the correct answer emphasizes that these devices instruct drivers on stopping, proceeding in certain directions, or limiting their speed, thereby ensuring compliance with traffic laws and regulations.
