Don’t let these restricted roads keep you from getting out into the fresh air with your bicycle! Here are a few general safety tips to keep you and other vehicles safe on the roads you share.

8 Safety Cycling Tips that Will Ensure a Safe Ride

  1. Follow the Rules of the Road. By law, you as a cyclist are required to obey the same laws and signs as motor vehicles. This also includes riding in the same direction as automobile traffic.
  2. Be Predictable. You may or may not know this, but it is required by law to use hand and arm signals to obviously indicate to vehicles around you your intentions to stop, merge or turn. Try and ride in as straight a line as possible. Avoid sidewalks–neither motorists nor pedestrians expect bicycles on sidewalks, because pedestrians have the right-of-way. If you must ride on a sidewalk, ride at a walker’s pace, and be very careful of other pedestrians. (In the Salt Lake City Downtown Central Business District NO BICYCLING IS ALLOWED at all.
  3. Be Visible. Wear bright colored clothing. Or reflective clothing, especially at night. Make sure your bike is outfitted with good reflectors. Reflectors at night are also required by law.
  4. Be Alert.
  5. 5. Ride with Proper Equipment. ALWAYS wear a helmet! Make sure that the helmet properly fits on top of your head, if it tips backward or forward on your skull, it does NOT properly fit. The Bicycle Helmet Safety Institute ( has staggering statistics. A study in New York City over the course of a decade showed clearly that helmets are a factor in fatal statistics. 74% of fatal crashes involved a head injury. 97% of all bicyclists who died were not wearing a helmet. Among serious injuries, only 13 % were wearing helmets.
  6. Especially at intersections, when the drivers of other vehicles have their attention strained. Cars turning do not necessarily have the vision or focus to see you. Vehicles exiting driveways also can be dangerous, as they are focused on oncoming traffic, they could easily not see you as they are looking towards cars. Make eye contact with drivers–assume they do not see you, until you are absolutely certain they do.
  7. Avoid hazards on the road: i.e. storm drain grates, manhole covers, oily pavement, gravel and ice. Cross railroad tracks at right angles. In the rain or wet road conditions, you should even avoid paint on the road, because the paint becomes slippery, and can easily catch a tire without enough friction and cause even the most experienced of cyclists to fall.
  8. Don’t listen to music or talk on the phone while riding. You should not have the mental distraction or the hearing impairment.

As you avoid the very few restricted roads around Utah, and if you keep this advice in mind, you will greatly reduce the risks involved with riding a bike on major roads. In the meantime, enjoy the MANY roads welcome to cyclists around Utah, and soak up the sun and fresh air!
