• Ensure vehicle is moving 10–15 mph (16–24 km/h) slower than posted ramp
speed for entrance or exit ramps. Failure to comply may result in vehicle rollover,
causing damage to vehicle or injury or death to personnel.
• ABS technology is designed to maintain rolling traction and steering. The rolling
action may produce longer stopping distances on some surfaces, such as freshly
fallen snow or loose gravel. The ABS steering advantage outweighs any braking
disadvantage on these surfaces. Evasive steering techniques are designed to allow
the driver to steer the vehicle clear of damage. By maintaining a speed reduction
without wheel lockup, ABS increases steerability of the vehicle. The driver should
use just enough steering movement to adjust the vehicle to a clear space on the
roadway.
• Avoid steering more than necessary to clear an obstacle. Oversteering may cause a
skid, jackknife, or rollover. Failure to comply may cause damage to vehicle or injury
or death to personnel.
• Do not drive faster than road or weather conditions permit. Maximum safe speed
limit for normal highway driving is 55 mph (88 km/h).
• Stopping can be adversely affected by poor road/weather conditions. Drive at a
slow, safe speed in poor conditions to avoid excessive braking. Failure to comply
may result in damage to equipment or serious injury or death to personnel.
• Do not pump brakes that are locking on a vehicle equipped with ABS when
stopping. ABS will automatically release wheels that are locking and apply
pressure to the other wheels. Failure to do so may result in damage to vehicle or
injury or death to personnel.
