Safe Teen Driving Blog

Many teens are so excited to get their driver's licenses that much of the training they received prior to licensure is quickly forgotten. But it's important for new drivers to follow the fundamental rules of the road, and adapting speed to conditions is one rule that's frequently broken.

Driving too fast for conditions is considered speeding and can result in a traffic ticket. But that's not the only reason to slow down - driving too fast for conditions is a contributing cause of many motor vehicle crashes. Motor vehicle crashes are the leading cause of death for 15- to 20-year-olds (based on 2005 figures, which are the latest mortality data currently available from the National Center for Health Statistics).

A 2009 analysis of speeding-related crashes by the National Highway Traffic Safety Administration (NHTSA) shows that following the speed limit is not enough to prevent a crash when conditions warrant a reduction in speed. The study showed that in speeding-related crashes that caused one or more injuries, 26% of the crashes were contributed to be exceeding the posted speed limit, while 74% were due to driving too fast for conditions. In property-damage-only crashes where speed was a contributing factor, 18% of the crashes were due to exceeding the posted speed limit and 82% of the crashes were contributed to by driving too fast for conditions.

Drivers should reduce their speed:
-immediately when it begins to rain. Roads become very slippery just after the rain begins, because the rainwater mixes with oil on the road that has been dropped from passing vehicles. Driving too fast on wet roads can result in skidding, when the vehicle loses traction with the road and the driver loses control of the vehicle.
-when roads are slippery due to snow or ice. Vehicles have even less traction on snowy or icy roads than they have in rainy weather. On icy roads, drivers should slow to a crawl and get off the road as soon as possible.
-in foggy or smoky conditions. Fog and smoke make it difficult to see ahead, and reducing speed reduces stopping distance.
-before a curve. Too often, drivers realize that they are moving too fast when they are already in the curve, but lowering speed in a curve results in a loss of traction that could cause a skid. Always reduce speed before entering the curve.
-in construction zones. Lower speed limits are usually posted in construction zones, but the new speed limit may not be low enough, especially for new drivers. The distraction of all the activity in the work zone and changes in the road surface can cause more difficulties for drivers who are inexperienced.
-around school zones and playgrounds. Again, lower speed limits are posted in school zones, but children are often present when the lowered limits are not in effect. Children are unpredictable and may walk, skate or bike into the road without checking for traffic.
-at night. Visibility is reduced at night; street lights and the vehicle's headlights cannot entirely make up for this.

It's also important to monitor your speed carefully on rural roadways with higher speed limits. Since the speed limit is already high, it's easy to drive too fast for conditions, which often include curves, animals, farm equipment, and roads that are not well-maintained.

Pressure from teen passengers should also be considered. Passengers may encourage the driver to travel at or above the speed limit. Resisting this pressure is an important exercise in maturity for teen drivers and is an integral part of keeping their driver's licenses. Unfortunately, it could even be a life-and-death matter.

A complete driver-training program includes lessons on all types of streets and highways, both night and day, in a variety of weather and traffic conditions. But many teens get the majority, if not all, of their driver training on familiar roads close to home. Some young drivers do not make their first expressway trip until after they are licensed and driving on their own. This is a high-risk method for teens to gain driving experience, because:

-Young drivers who don't have freeway experience have trouble controlling vehicles traveling at high speeds
-Teens have minimal experience in dealing with emergency driving situations, particularly at high speeds
-When expressways are unfamiliar to drivers, they spend more time searching the driving scene for directional signs and landmarks
-Teens often aren't aware of the level of risk on interstates, so they may continue other risky driving behaviors, such as nonuse of seat belts and allowing distractions such as loud music and noisy passengers
-Though expressways have a low incidence of collisions, the crashes that do occur have high injury severity rates because the higher speeds exponentially increase the amount of force involved in the crash

Commentary driving is an excellent way to train teens to drive safely on the expressway. With commentary driving, teens maintain a running dialogue of their progress - what they notice as they observe the roadway and what actions they will take: "The car in front of me is slowing down, so I'm slowing down and checking my following distance. My exit is coming up in one mile, so I'm putting on my turn signal, checking my mirrors and blind spot, and moving into the exit lane. The exit ramp has a posted speed limit of 45 mph, so I'm slowing to that speed. It's starting to rain, so I'm increasing my following distance."

Commentary driving forces the driver to use critical thinking skills to make driving decisions. The fact that the driver's observations are verbalized is comforting to the person (typically a parent) teaching the teen to drive, because it allows the instructor to follow the teen's thought process and quickly make corrections without lecturing, which teens tend to tune out anyway.

Teens often feel awkward about commentary driving, so it is helpful to model it for them prior to beginning driving lessons. This also allows parents to perfect the process and to see the roadway with new eyes, thus relating better to the beginning driver.

From a practical standpoint, it is obviously important for teens to work up to practicing driving on the expressway. The first several lessons should occur during non-peak hours on dry roads during the daytime. Introduce one variable - nighttime hours, rainy weather, rush-hour traffic - at a time, and ensure the teen is completely comfortable with each before progressing to the next.

The following training tips will help teens be safer drivers on the freeway:
-Make sure the teen understands that though traffic on the expressway can seem predictable because everyone is moving in the same direction at approximately the same speed, surprises can occur and drivers must be ready to deal with them at all times.
-Use commentary driving to make sure teens know how to identify interstate interchanges, signs, lane markings, and speed limits.
-Help teens learn how to enter and exit expressways properly: searching the road ahead, signaling, evaluating other drivers' speed, calculating the amount of available space, adjusting speed to the flow of traffic, identifying exits early, and following exit ramp speed limits. Practice entering and exiting the freeway at different points to broaden the young driver's experience.
-Include information in the lesson plan on how high speeds affect following distance, stopping distance, and the physics of motor vehicle crashes. To avoid overloading the young driver, provide these lessons off the road, or have teens take a driver safety course and report what they learned.
-Help teens understand how the steering needs of vehicles change at high speeds; excessive steering can cause drivers to lose control on the expressway.
-Reinforce that driving must be taken seriously; many traffic games occur on freeways. Make sure teen drivers maintain a steady lane position in the right lane, except when passing, and refrain from being competitive with other drivers.
-Talk about the dangers of the expressway, such as crosswinds when traveling on bridges or through mountain passes, other drivers tailgating them, and sharing the road with large trucks, and how to handle each one.
