From time to time we will be posting tips to ride predictably and safely in traffic. For more quick tips we recommend that you visit the well written handouts on the Philadelphia Bicycle Ambassadors website -http://www.bicyclecoalition.org/content/ambassador-handouts
Riding Near Parked Cars
Don’t weave in and out of parked cars, because you’ll confuse drivers; ride in a
straight line. Ride at least 4 feet away so you don’t get hit if someone opens their door. On narrow low-moderate speed streets aligning your bike with the right tire track of automobiles is a good rule of thumb.
When riding in bike lanes next to parking orient your bike to the left side of the lane. The minimum bike lane width in Philadelphia is 5 feet wide and normally parked cars are about 1 foot in from the right hand stripe. If you feel unsafe in the bike lane then adjust your road position accordingly, regardless of the left hand stripe of the bike lane.
Always scan behind you for oncoming traffic before changing lanes including bike lanes.
