Even if you are driving under the posted speed limit, you may be given a ticket or citation for driving too fast for the conditions. Driving too fast for conditions is defined as traveling at a speed that is greater than a reasonable standard for safe driving.
Examples of conditions where drivers may find themselves driving too fast include wet roadways (rain, snow, or ice); reduced visibility (fog); uneven roads; construction zones; curves; intersections; gravel roads; and heavy traffic.
In Oregon, the Basic Speed Rule (ORS 811.100) governs driving too fast for conditions, regardless of the posted speed limit. This rule requires drivers to consider the current conditions of the road, weather, visibility, and traffic, and to drive at a speed that is safe for these conditions. If a driver is traveling at a speed that is unsafe for the current conditions, they can be cited for violating the Basic Speed Rule, even if they are driving below the posted speed limit. Conditions that might warrant driving at a reduced speed include inclement weather like rain, snow, or ice, reduced visibility due to fog, construction zones, uneven or gravel roads, curves, intersections, and heavy traffic. Law enforcement officers have the discretion to determine what constitutes a reasonable and safe speed given the circumstances, and drivers are expected to exercise good judgment to avoid accidents and ensure safety on the roads.
