Which of the following cannot be operated on the highway without a Virginia inspection sticker?

The answer indicates that used vehicles in dealership inventory cannot be operated on the highway without a Virginia inspection sticker. This is because all vehicles, including those held by dealerships for sale, must comply with state inspection laws to ensure they meet safety and emissions standards before being driven on public roads.

In Virginia, a vehicle that is sold or operated must be inspected regardless of its status as new or used. New vehicles typically come with a temporary tag and may have a grace period before requiring a standard inspection. Government vehicles generally have different regulations and may not adhere strictly to some commercial standards. Vehicles with expired registration cannot be operated legally on the highway, but they do not directly pertain to the inspection requirement as highlighted in the question.

Thus, it is essential for used vehicles in dealership inventory to have a valid inspection sticker to verify they are roadworthy and comply with all necessary regulations before allowing them to be driven on highways. This requirement helps maintain safety standards and protects both the driver and others on the road.
