You are driving on a freeway and realize you've forgotten something at home. Is it permissible to make a U-turn?

Making a U-turn on a freeway is not permissible at any time. Freeways are designed for high-speed traffic and do not allow for frequent stops or turns due to safety concerns. The movement of traffic is continuous, and making such a maneuver could pose significant risks to yourself and other road users. Freeways typically have restricted access points, and any U-turn could disrupt the flow of traffic and lead to accidents.

Instead, the safest approach if you realize you've forgotten something at home is to continue driving until you reach the next exit. At that point, you can safely turn around and head back to retrieve what you need without violating traffic regulations or endangering yourself or others on the freeway.

This understanding emphasizes the importance of adhering to traffic laws designed to keep all motorists safe, particularly in high-speed environments like freeways.
