Which statement correctly describes the first thing to check before passing on a two-lane road?

• A. Signal and pass immediately
• B. Check the road surface
• C. Make sure it is legal, and the left lane is clear of oncoming traffic
• D. Look in the rearview mirror

Answer: (C)

Before you start to pass on a two-lane road, the first and most important check is to make sure you may legally pass and that there is no oncoming traffic in the left lane. This means being in a designated passing zone and having a clear view far enough ahead to complete the pass safely without forcing vehicles in the opposite lane to slow or brake abruptly. If it’s legal and the oncoming lane is clear, you can then signal and proceed with the maneuver. Looking in the rearview mirror helps you monitor traffic behind, but it won’t tell you whether there’s approaching traffic in the opposing lane or whether passing is allowed. Checking the road surface matters for traction, but it doesn’t establish whether the pass is permitted or safe from oncoming vehicles.
