General Rules
General driving – If you back your vehicle, look carefully and move slowly. Drivers do not expect a vehicle to be backing towards them and may not realize it until it is too late.
If you miss your turn or exit, do not back up, but go on to the next turn or exit or where you can safely turn around. It is illegal to back up on a shoulder or a freeway.
Do not stop in travel lanes for any reason (confusion, breakdown, letting out a passenger). Keep moving until you can safely pull off the road.
On a road with two lanes traveling in opposite directions, you must drive on the right side of the road except when you are legally passing another vehicle.
On a road with two or more lanes traveling in the same direction, stay in the right lane except to pass.
On a road with three or more lanes traveling in the same direction, if there is a lot of entering or exiting traffic, use the center travel lane. Unless directed to do so by officials or signs, never drive on the shoulder of the road.
Passing – On a road with two lanes traveling in the same direction, the left-hand lane is intended to be used for passing slower vehicles.
On roads with more than two lanes traveling in the same direction, use the right lane for slower speeds, the middle lanes for higher speeds, and the left-hand lane for passing only.
If you pass on the right, the other driver may have difficulty seeing you and might suddenly change lanes in front of you. Never pass on the shoulder, whether it is paved or not. Other drivers will never expect you to be there and may pull off the road without looking.

Kung susundin yan, hindi na kailangan pang gumamit ng "pitik" ng ilaw at lalo na ang busina.
Dapat aware ka sa paligid mo. Kung nasa fast lane ka tapos may mas mabilis na paparating sa likod mo, lipat ka na sa kanan. Kahit pa nasa max speed ka na, kung may mabilis sa'yo, dun ka sa kanan.
