Many roads have two or more lanes going in your direction. Drive in the lane that has the smoothest flow of traffic and is less congested.
If there are only two lanes going in your direction, pick the right lane for the smoothest driving. Don't weave.
If you can choose among three lanes on your side of the road, pick the middle lane for the smoothest driving. Use the left lane to go faster, pass, or turn left. Use the right lane to drive slowly, enter, or turn off the road.
Position your vehicle to keep up with the traffic flow. If other drivers are going faster than the speed limit, slow down and move to the right. You should never exceed the legal speed limit.
Don't drive in the blind spot of another driver or drive in bunches. Try to keep other vehicles out of your blind spots.
