Why
A SPEED LIMIT sign posts the maximum lawful speed for good conditions, here 50 mph. It is not a required or minimum speed, and you should go slower when rain, fog or heavy traffic make 50 mph unsafe.
Tip The posted number is a ceiling for perfect conditions; in bad weather the safe speed is often lower.
