Which centerline marking prohibits passing by traffic in both directions?
Correct answer: C – Two solid yellow lines
Two solid yellow centerlines separate opposing traffic and mark a two-direction no-passing zone. Drivers traveling in either direction may not cross these lines to overtake another vehicle. Kentucky has adopted the MUTCD standards that establish this meaning for centerline markings.
