Drivers meeting and following bus must stop. 8. Uncontrolled intersection  — stop when signals are not working. PASSING SAFELY It is equally important to know when not to pass as well as when to pass.  Collisions resulting from improper passing are often fatal since the impact force  is great in this type of collision.  The decision as to whether or not to pass another vehicle is determined by the  judgment and attitude of the driver. Be patient. Passing is not a game. Learn the  following passing rules well and practice them each time you con- sider passing  another vehicle.  1. Stay well back from vehicle ahead for better sight distance. Check rear vision mirror. Signal left turn to left lane. 2. Check well ahead for no passing zone and oncoming vehicles. Do not swing out across center line for a look. 3. Sound your horn to warn the driver ahead of your intention to pass. 4. Pass on left at a safe distance and do not return to right lane until safely clear of overtaken vehicle. 5. Signal right turn to return to right lane. Be sure to cancel signal light.
