What type of insurance must applicants prove before their road test?

Applicants are required to prove liability insurance before taking their road test because this type of insurance is legally mandated to operate a vehicle. Liability insurance protects other drivers and their property in case of an accident where the insured driver is at fault. It ensures that if an accident occurs, the costs associated with property damage or bodily injury to others can be covered.

In the context of the road test, demonstrating liability insurance not only aligns with state laws but also signifies that new drivers understand the importance of financial responsibility when they are on the road. Comprehensive and collision insurance, while also important for drivers, are not necessary to demonstrate at the time of the road test. Health insurance does not pertain to vehicle operation and hence is unrelated in this context.
