Bikers enjoy a freedom that many automobile drivers can only imagine. The thrill of the open road and the sense of adventure that goes along with it can be very addictive. But staying safe is important, which could explain why bikers ride so close to the yellow line. Scanning the road ahead for any potential problems is crucial, and it's a strategy known as the 12-second rule. If you're a biker, it could very well save your life.

The 12-second rule is about being aware of what's in front of you for 12 seconds down the road. Think about someone driving a car and visually scanning the intersection ahead, or noticing another car that could be turning out into the road in their lane. It's defensive driving: anticipating what could go wrong and taking steps to avoid potential disaster if the worst happens. For bikers, it all comes down to speed. For example, at 30 miles per hour, you should be focusing on the road about 528 feet in front of you. The faster you go, the farther you need to look.

But bikers using the 12-second rule aren't only aware of just the vehicles in front of them. They're also paying attention to pedestrians and possible road hazards. Once the rider spots a danger, they can slow down or even pull into a parking lot or other safe location, if need be. In the end, the 12-second rule improves reaction time and keeps the biker safe.

The 12-second rule is just one method that bikers can use to remain safe on the road. There's also the 2-second rule which involves staying at least 2 seconds behind the vehicle that's in front of them. The 4-second rule is also one that every biker should know, and it involves the path directly in front of them. Altogether, the 2-4-12-second rule is known as Rider Radar and is part of the Motorcycle Safety Foundation's basic rider course.

The MSF teaches riders important safety techniques since motorcycles can be dangerous according to the data, and the organization also educates drivers through a special program. "For Car Drivers" details several ways that drivers can do their part to ensure everyone's safety. It begins with keeping an eye open for bikers. It also includes not getting distracted while driving, using turn signals, and not throwing trash onto the road.

The MSF dates back to 1973, during a time when motorcycle manufacturers including Harley-Davidson and Kawasaki, pushed for a standardized education program. Over the years, the MSF has established itself as the leader in rider education. In fact, the MSF certifies bikers through its courses not only in the U.S. but around the world as well. Over 400,000 bikers take the organization's courses per year, with the MSF's operator manual used as the study guide in more than 40 states.
