This occurs because the load-carrying capacity, which includes the number of passengers and cargo or a combination thereof, has been exceeded. perating any type of vehicle while exceeding its Payload Rating is unsafe and increases the risk of accidents.

Direitos reservados CEPA © 2005 CEPA TIPS 2005 Overloading * Passenger Vehicles Copyright CEPA © 2005 Concentrated in the trunk/boot/cargo area, the load modifies the vehicle’s center of gravity making it unstable. Weight distributed excessively on the rear axle alters the static and dynamic balance needed to safely operate a vehicle. Normally, the overload occurs on the rear axle, thus modifying the vehicle’s handling even in the simplest situation: Starting out During accelerations During overtaking maneuvers While riding uphill While negotiating curves

Direitos reservados CEPA © 2005 CEPA TIPS 2005 Overloading * Passenger Vehicles Copyright CEPA © 2005 Tire grip is critically affected because it is directly associated with weight distribution. Hence, by concentrating the weight on the rear axle, the footprint of front-drive tires is significantly reduced. In comparison to rear axle tires, front tire grip and traction are lower, something that compromises handling and steering precision. Under-inflated tires can cause excessive heat buildup, thus leading to tire failure (most frequently blowouts).

Direitos reservados CEPA © 2005 CEPA TIPS 2005 Overloading * Passenger Vehicles Copyright CEPA © 2005 An overloaded vehicle’s stopping distance will increase significantly due to the effect of the uneven weight distributed on the suspension and brake system. The vehicle’s path of travel may also be adversely affected, especially when the driver has not adequately anticipated this situation by slowing down, braking progressively, and ensuring s/he has enough time and space to stop.

Direitos reservados CEPA © 2005 CEPA TIPS 2005 Overloading * Passenger Vehicles Copyright CEPA © 2005 This is where lack of stability can best be noticed, because the vehicle’s center of gravity has been excessively shifted back. This point concentrates the effect of the centrifugal force in curves. The dynamic weight shift, while negotiating a curve, could induce loss of control if drivers fail to adequately adjust their travel speed. On slippery or irregular surfaces this risk is remarkably higher. To avoid running off the road, the driver of an overloaded vehicle needs to slow down earlier than usual.

Remember that an overtaking maneuver will require more time and space to be completed safely. Avoid overtaking mainly in single- lane two-way roads. If you notice that the other driver is about to overtake, do not jeopardize the situation by a sudden braking maneuver, an acceleration, etc.

Under-inflated tires can lead to blowouts. Damage to the suspension takes place more frequently in overloaded vehicles. Brake overheating and wear are accentuated by hauling excess weight. Insurance policies normally carry exclusion clauses regarding vehicles transporting a number of passengers or load in excess of their rated capacity.

Check electrical system: battery charge, lights, windshield wipers, etc. Inspect wheel alignment and balancing at recommended intervals Set headlight alignment according to the load being transported. Remember to carry an emergency kit. Know your vehicle’s Load Carrying Capacity (Payload) Do not exceed the maximum payload rating Do not transport loose objects Conveniently store and/or secure loads Distribute the load evenly Check tire inflation pressure in relation to the transported load (including spare tire)
