What should a driver do if their vehicle is disabled and unable to travel on the expressway?

Answer: D — Move the vehicle off the roadway if possible

If a vehicle becomes disabled on the expressway, the safest course of action is to move the vehicle off the roadway if possible. This is crucial for several reasons. First, it helps to prevent further accidents by allowing other vehicles to pass safely without having to navigate around an obstruction. Expressways often have high-speed traffic, and staying on the roadway can put both the driver and other motorists at risk. Additionally, moving the vehicle off the roadway provides a safer environment for both the driver and any passengers. Once the vehicle is in a secure location, the driver can then take the necessary steps to call for assistance without fearing for their safety due to oncoming traffic. While staying in the vehicle may seem like an option, it is only advisable if the vehicle is in a perilous position that cannot be moved safely. Overall, moving the vehicle off the roadway is a proactive approach to ensuring safety and minimizing potential hazards for everyone on the expressway.
