Is it lawful to operate a vehicle with the transmission lever in neutral while descending a grade to conserve fuel?

• A. Yes
• B. No
• C. Only in emergencies
• D. Only for commercial vehicles

Answer: (B)

Operating a vehicle with the transmission lever in neutral while descending a grade is unlawful and unsafe. This practice, often referred to as "coasting," can significantly diminish the driver's control over the vehicle. When in neutral, the vehicle is unable to use engine braking, which is important for maintaining control, especially on slopes.

Additionally, coasting can increase the risk of accidents, as it reduces the driver's ability to respond quickly to obstacles or changes in traffic conditions. Many jurisdictions have specific laws that prohibit this practice because it compromises safety not just for the driver but also for other road users. Therefore, keeping the vehicle in a suitable gear while descending a grade is crucial for safe operation.
