Operating a vehicle with one fourth of its leaf springs broken or missing is illegal because leaf springs are crucial components of a vehicle's suspension system. They help support the weight of the vehicle and maintain control and stability while driving. If any part of the leaf spring system is compromised, it can lead to serious safety hazards, such as difficulty in steering, increased stopping distance, or even loss of control of the vehicle. Maintaining the integrity of the suspension system is vital not only for the safety of the driver and passengers but also for others on the road. Regulations prohibit operating a vehicle in such a condition to uphold safety standards. Therefore, it is illegal to drive a vehicle with broken or missing leaf springs, regardless of the weight of the vehicle or load it is carrying.
