You drive on a narrow two-lane road. Ahead is a sharp curve, and trees hide the road beyond it. When should you reduce your speed?
Blue A approaches a sharp curve on a narrow two-way road. Trees stand inside the curve and hide the road beyond. The road has double yellow center lines.
Correct answer: Before the curve, so you can stop for a hazard that you cannot see yet
Why
Utah's basic speed law names curves, hill crests, and narrow or winding roads as places where you must slow down. Brake before the curve while your wheels are straight, and keep a steady speed through it. Stay well to the right in your lane, because an oncoming vehicle can be hidden around the curve. Never pass when a curve blocks your view.
