What does a red arrow signal mean?

A red arrow signal indicates that drivers must stop and are prohibited from proceeding in the direction the arrow is pointing. This signal is used to control traffic at intersections and to prevent vehicles from making a turn that could interfere with oncoming traffic or pedestrians. The red arrow is a strong visual cue for drivers, emphasizing the need to halt their movement to ensure safety.

In contrast, options suggesting that drivers can proceed with caution or prepare to yield do not align with the strict directive that a red arrow conveys. Similarly, the idea of speeding up to beat the traffic light contradicts traffic safety principles and the clear message of the red arrow, which prioritizes stopping and maintaining the flow of safe traffic.
