Bicyclists must abide by all the same road rules that bind motorists. You should obey all traffic laws, including stopping at stop signs and red lights and yielding to the right-of-way.
You should also note that bicyclists aren’t allowed to carry passengers on a bicycle in Georgia. You cannot have more than one person on your bike at a time. If you’re over the age of 12, you’re also not permitted to ride on sidewalks unless a local ordinance allows it.
