A 3-minute lesson from the Nevada course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Some Nevada freeways have signals hanging over each lane and carpool (HOV) lanes. Read the symbol over your lane: a green arrow means go, a yellow X means use caution or merge, and a red X means get out of that lane.

Signal
Meaning
Green down arrow + OPEN
You may drive the posted speed limit in this lane
Yellow X + CAUTION
You may use the lane; watch for slow traffic or debris
Yellow X + MERGE
The lane is ending — prepare to merge safely
Red X + CLOSED
Do not drive in this lane; merge into an open lane
Overhead freeway signals post reduced speed limits and lane closures for construction, debris, crashes or other reasons, update as you get closer, and show all lanes open once you're past.
Overhead signals at a crash: right three lanes closed, speed limit posted
HOV lane
A high-occupancy vehicle lane restricted to encourage ridesharing and public transit, remove congestion from normal lanes, and improve traffic operations.
You're alone in your electric car and the HOV lane is moving faster. You can't use it — electric cars need 2+ people. With a passenger, even a baby, you could enter where the line is broken white.
