Common features of these rollovers: • Speed (80 km/hr can be too fast !!) • All are 4 WD high Centre of Gravity cars • 8 on straight roads • 8 classic “S” curves: • driver loses concentration and veers slowly left or right • wrong steering reaction: pulls hard left/right • wrong braking reaction: brakes whilst steering • 4 on blacktop roads at high speed • 1 tyre blow-out, 1 junction/speed
4WD are great cars: • They are strong (we think) • They can go anywhere (almost) • You (almost) never get stuck • You sit high (good view) • They are powerful & feel good (macho?) • They are comfortable • They can carry a lot of load and people BUT…….
But 4WD: • Have a very high CoG: this means that they are more sensitive to rollovers. • They do not brake that well: they are very heavy. • They do not steer and corner that well: they are heavy and high. • They give a false sense of security: driver feels invulnerable at any speed. • They are powerful and can go very fast: much too fast for their handling ability.
Low CoG Rollovers & Centre of Gravity High CoG Would you drive these cars in the same manner when taking a corner or bend ??? Of course NOT !!!4WD High CoG car: adjust your driving & speed.
When driving a 4WD: • Adjust your driving style. Combination of: • Speed • Steering: no sudden changes of direction • Braking: start braking earlier, keep more distance • Keep heavy loads as low as possible: NOT on the roof! High loads make the car more unstable. • Keep loads balanced to the centre/middle. • Passengers are also load: they change the stability of the car.
The classic “S” curve rollover: Mistake 1: lost concentration car moves slowly to the right (or left) Mistake 2: pull hard left could roll here already Roll? Mistake 3: pull hard right Roll!! Mistake 4: braking & turning at the same time
The classic “S” curve rollover: How to avoid it !!! Mistake: lost concentration car moves slowly to the right (or left) Good re-action: Roll-out into the desert. Do NOT pull your steering wheel. Hold it tight and straight with 2 hands. Brake slowly to full STOP. Do NOT panic.
How to protect yourself against rollover? • Use a 2-WD instead of a 4-WD if possible. • If you drive a 4-WD: adjust your driving. • Never make violent adjustments in your steering & your braking, you must avoid an uncontrolled skid. • Make sure a 4-WD has a roll-bar !!!!! • Wear your seat belts !!!!! Your BELT can Save your LIFE
