Is it generally permissible to make a U-turn on expressways?

Making a U-turn on expressways is not allowed because expressways are designed for higher-speed traffic and maintaining traffic flow. Allowing U-turns in these areas could create dangerous situations, such as abrupt stops or slowdowns that can lead to accidents. The presence of high-speed vehicles and the limited access points on expressways mean that U-turns would disrupt the smooth movement of traffic and increase the risk of collisions. Therefore, drivers are expected to adhere to specific laws that prohibit such maneuvers in order to ensure safety and efficiency on these roadways.
