A curve in the road is a bend. If the bend is very severe, it is a hairpin-bend.

a curve... Well that could be an answer however it is not possible to have a bend or a curve 'in' a straight road. A curve or bend is, by definition, after the end of one straight section and before the beginning of the next; so it can not be 'in' a straight road.
The curve in the road was thick with ice, causing many accidents on the highway.
When approaching a curve to the right on a narrow road you should make sure you slow down to keep your tires on your side of the road. Oncoming traffic will need to maintain tight control to navigate the curve and will fight drifting into the opposite lane on the curve.
When a car is on a curve, centrifugal force tends to force it outwards. Normally, this force is resisted by the car's tires gripping the road surface. However, ice on the road reduces the friction and therefore the tires cannot grip so well.
