Curve With 35 MPH Advisory Sign
Curved road ahead, safe speed is 35 MPH
In short: A yellow curve sign with a 35 MPH plaque warns of a curve ahead and gives 35 mph as the advisory speed judged safe for it. Slow to 35 or below before entering the curve — and go slower still in rain, ice, or poor visibility, since advisory speeds assume dry pavement.

What to do
Reduce speed to 35 MPH or slower before curve.
Tips
Advisory speeds assume dry pavement and good tires.

About warning signs
Warning signs are diamond-shaped and yellow with black symbols. They alert you to hazards ahead — curves, intersections, crossings — so you have time to slow down. On the DMV written test, expect several questions asking what a specific warning sign means and what action it calls for.
Practice the rule this sign carries
The 'Basic Speed Law' means you can be cited for unsafe speed even when:
- A. Driving 5 mph over the limit in clear weather
- B. Driving exactly at the posted speed limit
- C. Driving below the posted speed limit if conditions are hazardous
- D. Driving on a road with no posted speed limit
Show answer
C. Driving below the posted speed limit if conditions are hazardous — The Basic Speed Law requires you to drive at a speed safe for actual conditions — fog, rain, heavy traffic, or road hazards may require driving well below the posted limit. The posted limit is the maximum, not a guaranteed safe speed.
