ENTER A CURVE SLOWLY

Speed limits posted on curve warning signs are intended for passenger vehicles, not large trucks. Large trucks should reduce their speed even further. Studies have shown that large trucks entering a curve, even at the posted speed limit, have lost control and rolled over due to their high center of gravity.

40 percent of speeding-related fatalities occur on curves.

Braking in a curve can cause the wheels to lock up and the vehicle to skid.
