Advisory speed plaque
What does it mean?
A yellow advisory-speed plaque supplements a warning sign with a speed recommendation for the condition ahead. The pictured 35 MPH is an example for the warned condition, not a new general regulatory limit or a guarantee of safe speed in rain, ice, or other poor conditions.
What to do when you see it
- Read the warning above the plaque to identify the condition the advisory speed concerns.
- Adjust speed before reaching the curve or other warned condition.
- Reduce speed further when visibility, traction, traffic, or your vehicle requires it.
How to recognize it
- Yellow rectangular plaque with black numerals and MPH lettering.
- The example displays 35 MPH.
- Used with a warning sign rather than as a separate general speed-limit sign.
On the road
A curve warning carries a 35 MPH plaque and the pavement is wet. Prepare for the curve before entering it and choose a speed suited to the reduced traction rather than treating 35 as a promised safe speed.
Don’t confuse it with
Speed Limit sign
A white SPEED LIMIT sign states a regulatory limit; the yellow plaque gives an advisory speed for the warned condition.
