What does a disabled vehicle sign look like?

A disabled vehicle sign is designed to alert other drivers to the presence of a vehicle that may be stationary due to mechanical failure or because it is disabled. The correct choice, which describes a rectangular orange sign featuring a black "disabled" symbol, effectively communicates this message. The orange color is particularly significant, as it is universally associated with caution and indicates that drivers need to be aware of potential hazards.

The specific symbol of disability used on this sign serves as a recognizable indicator, making it easier for other road users to identify the situation quickly. This is especially important for ensuring safety on the road, as it alerts oncoming traffic to the presence of a disabled vehicle that may not be moving and could pose a risk of accident if drivers are unprepared.

In contrast, the other options do not accurately represent the standard sign used for indicating disabled vehicles, either in shape, color, or symbolism, leading them to be less effective for this purpose.
