CEPA TIPS 2005



Some drivers only notice the problem when en route; they perceive that the vehicle is not responding to their inputs. 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.

CEPA TIPS 2005



• Extraordinarily• While traveling on vacation • While traveling on business

Sales Reps are an example of drivers who – as a regular part of their job – need to operate their sedans, wagons or other cars, loaded with product samples and sometimes, inadvertently, they exceed the vehicle’s load-carrying capacity.


CEPA TIPS 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


CEPA TIPS 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).


CEPA TIPS 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.


CEPA TIPS 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.


CEPA TIPS 2005



• Overloading also negatively compromises engine performance.

• 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.


CEPA TIPS 2005



• It is estimated that for every 50kg / 110lb of additional weight, the vehicle consumes approximately 2 to 3% more fuel.

• 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.


CEPA TIPS 2005



• Check brake, lubricant, cooling and windshield washer fluid levels.

• 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)
