Passing a Cyclist on a Double Yellow With Oncoming Traffic
You are driving a pickup truck eastbound on a two-lane rural road with a double yellow center line. The speed limit is 45 mph. Ahead, a cyclist is traveling eastbound at 15 mph, riding about 6 feet from the right edge to avoid a line of potholes. Your lane is 11 feet wide. The cyclist is wearing a helmet and has a rear light. Three cars are behind you; the closest is tailgating at about one second. Oncoming traffic is a steady line of cars; the nearest oncoming car is about 300 feet away and closing at 45 mph. It is dusk, and you have your headlights on. You are 100 feet behind the cyclist and closing at 30 mph.
1. May you legally cross the double yellow line to pass the cyclist in Georgia? What conditions must be met?
Read the worked answer
Georgia's safe-passing law requires a motorist to leave at least 3 feet when passing a bicyclist. Georgia also permits a driver to cross the center line, even a double yellow line, to give a cyclist that clearance when it is safe to do so. But the permission is conditional. You must have a clear view, enough time and distance to complete the pass without interfering with oncoming traffic, and no other hazard that makes the maneuver unsafe. You may not force an oncoming driver to slow or swerve. The double yellow line is not an absolute barrier in this specific passing situation, but it is a warning that the maneuver is exceptional and must be justified by the actual conditions.
2. Given the numbers in the setup, should you attempt the pass now? Show your reasoning.

No. If you pull into the oncoming lane at about 45 mph while the oncoming car is also at 45 mph, the two vehicles close at roughly 90 mph, or about 132 feet per second. The oncoming car is 300 feet away, so you have only about 2.3 seconds before a head-on conflict. You also need time to close the 100-foot gap to the cyclist at a 30 mph closing speed, then travel past the cyclist with 3 feet of clearance and return to your lane. That is likely 3 seconds or more in the oncoming lane. The available time is shorter than the required time, so the pass is unsafe. You should slow down, stay behind the cyclist, and wait for the oncoming line to clear.
3. What should you do about the tailgating driver behind you while you wait?
Read the worked answer
Do not brake-check or speed up to satisfy the tailgater. Braking suddenly could cause a rear-end collision, and speeding up would reduce your following distance to the cyclist and make a safe pass even harder. Maintain a steady speed or slow gradually, and increase your gap to the cyclist so you have room to react. Signal your intention to wait. If the tailgater remains dangerously close, pull off at a safe wide spot and let that driver pass. Your priority is to avoid a collision with the cyclist, the oncoming traffic, and the tailgater, in that order.
