Virginia Driver Education And Traffic Safety (VADETS) Practice Test

A newly constructed highway is likely to include rumble strips along the lane's edge as a safety feature. Rumble strips are designed to create a tactile and auditory warning for drivers who may be drifting out of their lane. When a vehicle inadvertently moves onto or over the rumble strips, the vibrations and sound alert the driver, helping to prevent potential accidents. This feature is particularly important for maintaining safety on highways where high speeds are common, and driver inattention can quickly lead to dangerous situations. Rumble strips serve to encourage drivers to remain focused and are an effective tool in reducing lane departure accidents. The other options, while they may be present on certain roads, do not serve the same purpose in terms of immediate driver awareness and safety. Curved barriers may be used to redirect traffic but are not as commonly featured as a lane's edge treatment. Paved shoulders provide structural support and a place for emergency stops but do not offer the alert function of rumble strips. High visibility markings, while crucial for guidance and awareness, primarily serve to define lane boundaries rather than alert drivers to a potential hazard.
