United States:
The bottom line is the safest lane to drive in is the one where you pay attention, leave a safe distance between you and the car ahead, give signals when you plan to change lanes, obey the left lane rules of the road.
On a state or interstate highway with two or more lanes in both directions the left lane is reserved for passing. It is not a lane to use for cruising at the speed limit and making all the other cars slow down. Its not to be used simply to avoid being in the right lane where ramps go on an off. More and more states are issuing violations for drivers who use that left lane while NOT passing, as they irritate the drivers in the long line of traffic that builds up behind them.
Most laws on United States highways reserve the left lane for passing and faster moving traffic, and that traffic using the left lane must yield to traffic wishing to overtake. That means if you are not keeping up with the traffic in the left land and are not passing cars in the right lane then you must pull over into the right lane. These laws refer to the "normal" speed of traffic, not the "legal" speed of traffic. So, if traffic flow is traveling at 60 mph in a 55 mph zone, the 55 mph driver is required to move to the right.
Slower moving drivers who hog the left lane trigger aggression in drivers who wish to pass and keep up with the left lane traffic speed. Aggressive drivers cause dangerous situations for other drivers when they reach their melting point.
If you are following a slower moving car in the right lane, put on your left turn signal, safely merge into the left land to pass the slower moving vehicle then signal right and safely merge back into the right lane once you have passed that vehicle.
The lane beside the roadway is the shoulder of the road if on a highway, and if on a regular street it may be a bicycle route or a turn lane.
A bicycle lane is a part of a roadway designated for use by cyclists.
A bike lane is another term for a bicycle lane or cycle lane - a part of a roadway designed for use by cyclists.
