It is important to slow down:

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

• On narrow or winding roads.
• At intersections or railroad crossings.
• When the road is wet or slippery.
• All of the above.
