I had compiled this list long back. Hope it helps and adds to the safety net.
Be considerate (Driving trivia) - Assume there is a free left at every junction and thus leave enough space on your left for others to turn off-course if you are not planning to do so! Fallback of the same statement: Move to the left lane /side if you want to turn left, move to the right lane/side if you want to turn right. Please do so with ample time and space in hand and not at the last moment!
Indicate (Driving trivia) - Use indicators to help others judge your intentions better. Use them for lane changes as well. Use them to inform about your intentions only and never to indicate what you, want the vehicle behind, to do!
Pressurized (Driving trivia) - Maintain manufacturer recommended air pressure in the tires. It affects Fuel Efficiency positively!
See more (Driving trivia) - The more you see, the safer you drive! Clean the windshield and the rest of the glasses + IRVM + Side RVMs + your own (if you have)! Go out and see the difference it makes to your view-span!
Lanes and not lames! (Driving trivia) - Follow lane discipline. Even if lanes are not marked, maintain an imaginary one and drive. Avoid unnecessary lane changes. It does not save much time. Do calculate the time difference and see it for yourself!
Live and Let Live (Driving trivia) - Use high-beam on unlit roads, switch to low-beam on seeing vehicles from the opposite direction and also if you get close to the vehicle in front. For all other scenarios use low-beam! Prioritize slowing down over switching to high-beam. Stop blinding!
Mind your stop (Driving trivia) - Always stop before the stop line at a red signal. Amber light means slow down and not speed up to get through the junction! Drive Safe! :-)
Buckle up (Driving Trivia) - Wear seat-belts for your safety and not because you got to pay up when caught. Ask co-passengers to buckle up as well. Drive and ride safe!
Know your blind spots (Driving trivia) - Always be aware of your blind spots and do head checks regularly to avoid being taken by surprise. Drive safe!
Hazard lights for hazard alone (Driving trivia) - Refrain from using hazard lights during rain! The vehicles on your right thinks you will turn right and the ones on your left thinks you will turn left. Spare the confusion! Use hazard lights only when your vehicle is static/broken down. Drive safe!
No rollers! (Driving trivia) - Refrain from keeping any items that might roll on to the floor of your car and create havoc by getting between your ABC's (accelerator-clutch-brake)'s. Drive safe!
No Tailgating (Driving trivia) - Do not tailgate. Follow the two-second rule to have the stopping distance within your reach! For more information:

It is difficult to follow it under heavy traffic scenarios, but since the speed will be less, damage if any will be less as well. Drive safe!
Know the blind spots of others (Driving trivia) - Avoid traveling in the "blind spot" of another vehicle. A good rule of thumb to remember when overtaking or following other traffic is "if you can't see their mirrors, they can't see you!" This is of utmost importance for the bikers! Drive safe!
Proper lane changes (Driving trivia) - Try and make your lane changes as smooth as possible so that no other vehicle need to react to your movements. Leave ample space and complete the lane change. Drive safe!
Footwear (Driving Trivia) - Drive wearing shoes ,preferably closed or which are tied to your feet. Never wear chappals, they might get stuck and cause panic. Drive safe!
Queue (Driving trivia) - There is something called queue. If ants can, so can we! Drive safe!
