What type of parking requires you to turn the wheels toward the road's side when there's no curb?

When parked on a roadway without a curb, the correct practice is to turn the wheels toward the side of the road. This action is a safety precaution designed to prevent the vehicle from rolling into the roadway if it were to move. Uphill parking, specifically, dictates that drivers turn their front wheels away from the roadway when there's a curb and toward the roadside when there isn't one. This helps ensure that the vehicle remains positioned safely and reduces the risk of accidents.

In contrast, diagonal parking and parallel parking have different positioning requirements and do not specifically address the situation of whether there’s a curb or not. Diagonal parking typically involves parking at an angle to the curb, while parallel parking requires the vehicle to be positioned parallel to the curb, relying on it for support. Downhill parking also has its own set of rules, where the wheels need to be turned toward the curb when applicable, rather than toward the side of the road. Therefore, understanding these parking rules in relation to the presence of a curb is crucial for ensuring vehicle safety.
