What is the purpose of reflective markings on large vehicles?

The purpose of reflective markings on large vehicles is primarily to increase visibility and safety during low-light conditions. These markings enhance the ability of other road users to see large vehicles, especially at night or in poorly lit areas. By reflecting light from other sources, such as headlights, these markings help to make the vehicle more recognizable and reduce the likelihood of accidents.

Increased visibility is critical for large vehicles, as their size and shape can make them harder to see compared to smaller vehicles. This is especially important when they are on the road with other vehicles or when they are stationary. Reflective markings alert other drivers to their presence, improving safety for everyone on the road.

The other options do not accurately capture the primary function of these markings; while appearance may play a minor role, safety is the foremost concern. Likewise, markings regarding load capacity are typically indicated by other means and not through reflective materials, and no responsible vehicle design would aim to confuse other drivers.
