What actions are prohibited under the Motor Vehicle Act?

The correct choice identifies a number of serious offenses that are explicitly prohibited under the Motor Vehicle Act. Impaired driving refers to operating a vehicle while under the influence of alcohol or drugs, which significantly increases the risk of accidents and endangers public safety. Driving without insurance is a critical issue as it leaves both the driver and others on the road unprotected in case of an accident. Speeding is another significant offense, as it can lead to a loss of control over the vehicle and is a contributing factor in many traffic collisions. These actions are all categorized as major offenses due to their potential to cause harm and their violation of traffic laws designed to ensure public safety.

While driving with a permit is not inherently prohibited, the context suggests that it refers to legal driving under the conditions established by the permit. Driving under the influence is one aspect of impaired driving, and although loud exhaust systems can be a nuisance and potentially violate local noise ordinances, they do not fall under the same severe category as the offenses identified in the correct answer.
