What does the sign 'Keep right' instruct drivers to do?

Answer: C — Drive to the right

The 'Keep right' sign instructs drivers to drive to the right. This sign is typically placed where there is a dual-lane roadway or where certain traffic patterns are in place, indicating that the right lane is the designated lane for travel. Adhering to this instruction helps maintain an orderly flow of traffic and ensures that slower-moving vehicles stay right, allowing faster vehicles to pass on the left. Remaining in the right lane is especially important in situations where there are exits or merging traffic, as it provides space for other vehicles to navigate safely. This signage also promotes safety by reducing the likelihood of collisions that may occur when vehicles are trying to switch lanes or overtake one another in congested areas.
