Navigating the nuances of regional road rules

The beauty of a country where states adjoin is the diversity of culture, history and experience that is contained within each set of borders. The challenge of it, though, is keeping up with road regulations that shift depending on which side of the border a traveler resides. When taking on the open road, one might not even notice crossing a state line. However, failure to adjust your driving habits can result in accidents, ticketing and fines that are likely to put a damper on any excursion. Watch out for these variances in regional road rules that can help keep you safe as you sojourn into the sunset.

Permissive vs. restrictive yellow lights

While we all know that a yellow light is the warning that precedes a red light, what to do with that information can vary from state to state. There are nine states (Connecticut, Iowa, Michigan, Mississippi, Nebraska, New Jersey, Oregon, Virginia and Wisconsin) in which entering an intersection during a yellow light is permissible only if it is the safest thing to do. Each one of these states borders a state (the remaining 37 and DC) where the opposite is true. A yellow light is considered permissive, and one can enter the intersection at any point during its duration. Especially during a multi-state road trip, it is important to be aware of these differences.

Sharing the road

Local traffic patterns can be shaped by expectations of who else might be on the road. A city populated by an abundance of cyclists and motorcycle riders may have drivers more prone to sudden stopping and starting, or other informal customs that can throw an out-of-town driver for a loop. In rural areas, horses and tractors on especially tight-and-winding roads present new conflicts for drivers unfamiliar with the region’s quirks.

Know your speed law

In some states, posted speed limits are more strictly adhered to by traffic cops and in courtrooms. In these states, it’s best to maintain a steady pace and stay vigilant about avoiding a speeding ticket. However, in certain states, the law advises that drivers should keep pace with the flow of traffic in order to avoid creating unsafe conditions in spite of what the posted speed limit might be. New York’s ‘Reasonable and Prudent’ and California’s ‘Basic Speed Law’ are both designed this way.

Distracted driving laws

Although every state in the union with the exception of Missouri and Montana has banned texting while driving, laws are blurry when it comes to other forms of cell phone usage. About half of all states ban any handheld cell phone use while driving and require drivers to rely on a speakerphone option if they take calls while in motion.
