RULES OF THE ROAD
(State of Colorado)
8. Safe driving tips
8.8. Hills and curves
You may not know what is on the other side of a hill or just around a curve, even if you have driven the road hundreds of times. If an obstruction is in the road just over a hill or around a curve, you must be able to stop.
A vehicle can travel much faster in a straight line than it can in a curve. If you go too fast, the tires will not be able to grip the road, and the vehicle will skid.
Always slow down before reaching the curve, and accelerate only after passing the middle of the curve.
