Oregon Following-Distance & Headlight Rules

Oregon defines a safe following distance as 2-4 seconds. For speeds greater than 30 mph, a safe following distance should be 4 seconds or more, to allow enough time to make a decision and respond.

Headlights are required: - From **sunset to sunrise** - **At any time** conditions make it difficult to see people or vehicles 1,000 feet ahead (rain, fog, dust, smoke, snow, etc.) In fog, dust, or smoke: use **low beams**. High beams reflect back and reduce visibility. Dimming rules: - Dim high beams when an oncoming vehicle is within **500 feet** - Dim high beams when following another vehicle within **350 feet** - Auxiliary lights (fog lights) must be off whenever you are required to dim headlights It is illegal to drive at night or in bad weather with only **parking lights** on. A vehicle stopped or parked on a road or shoulder in limited visibility must have parking lights on.

Oregon's manual does not give a specific count for following a motorcycle. It says only to allow more distance between your vehicle and a motorcycle than you would for a car, because motorcycles can stop more quickly than cars and small road hazards (gravel, potholes) affect them more.

Oregon does not specify a fixed minimum number of feet for passing a cyclist. At speeds over 35 mph, you may pass a person on a bicycle traveling in your lane only if you leave enough distance to prevent contact with them if they were to fall. If you cannot pass safely, you must slow down and remain behind the bicycle until it is safe to pass.

Oregon's move-over law applies to **any motor vehicle stopped with lights flashing**: emergency vehicles, tow trucks, road maintenance, disabled passenger vehicles, all of them. On a road with two or more lanes going the same direction, drivers must: - **Change lanes** away from the stopped vehicle (preferred), OR - If a lane change is unsafe or impossible, **slow down to at least 5 mph below the posted speed limit** and pass with as much room as safely possible. For active emergency vehicles using lights or sirens, drivers must pull as close as safely possible to the right side of the road and stop until the emergency vehicle has passed, then maintain at least 500 feet behind it.

The Oregon Driver Manual contains no named defensive-driving framework: SIPDE, IPDE, and the Smith System appear nowhere in the text. Its Defensive Driving section (p.73) gives narrative guidance instead: "Know how to adjust your driving to allow for problems with your vehicle, the type of road surface, poor weather, heavy traffic, poor lighting, and your own physical, mental, and emotional condition"; keep an unobstructed view to the front, sides, and rear of the vehicle; and "A defensive driver is always aware of their surroundings and possible escape routes."
