Before passing another vehicle on a two-lane road, you should:

Safe passing on a two-lane road requires: (1) checking that the oncoming lane is clear for the full distance needed to complete the pass and return to your lane safely — typically 700 feet or more at highway speed; (2) checking your mirrors and blind spot for vehicles already passing you; (3) signaling your intent; (4) moving into the oncoming lane and accelerating to clear the slower vehicle; (5) signaling and returning to your lane only after you can see the slower vehicle in your rearview mirror. Never pass where road markings prohibit it (solid yellow line on your side), near intersections, on curves, on hills, or where you cannot see the road ahead clearly. Honking before passing is sometimes appropriate but does not substitute for clear line of sight.
