2013 Oregon Driver Manual - Oregon Department of Transportation

Large trucks and combinations of vehicles cannot stop as quickly as
passenger vehicles. Give them more stopping room than a car.
The braking ability of vehicles can vary widely due to type and condition
of the pavement surface, the type and condition of tires and brakes, and
other factors. Study the table below. It takes longer to stop than you think.
On average, how long does it take to STOP?

When driving on a road with no center line, where vehicles come from
each direction, drivers must give at least half the road to others going in
the opposite direction.
At any time when you cannot avoid driving to the left of the center line,
you must yield to oncoming traffi c.
Avoid frequently changing lanes. Change lanes only when you can do
so safely.
Keeping Right
Drive on the right half of the road except when:
• Passing another vehicle going in the same direction as you.
• Driving to the left of center to pass an obstruction.
• A road is marked for one-way traffi c.
• A road has three marked lanes and the center lane is a passing lane.
• You are turning left.
• Directed by emergency personnel or other persons directing traffi c.
