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 Arizona, drivers must adhere to the 'Basic Speed Rule,' codified in Arizona Revised Statutes § 28-701. This rule mandates that drivers must not operate a vehicle at a speed greater than is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing. This means that even if you are driving below the posted speed limit, you can still receive a citation if your speed is considered unsafe for the current road conditions, such as during inclement weather, in construction zones, or in areas with heavy traffic. Law enforcement officers have the discretion to determine if a driver is going too fast for the prevailing conditions, and citations can be issued based on their judgment. It is the responsibility of the driver to adjust their speed to ensure safety regardless of the posted speed limit.
