Watch for brake lights from slowing vehicles. By seeing these things far enough ahead, you can change your speed or change lanes, if necessary, to avoid a problem. Road conditions: Look for hills and curves anything for which you will have to slow down or change lanes. Pay attention to traffic signals and signs. If a light has been green for a long time, it will probably change before you get there. Start slowing down and be ready to stop. Traffic signs can alert you to road conditions where you may have to change speed. i J < s I 1 Second Required for Each 10 Feet of Vehicle Length at Speeds Under 40 MPH Above 40 MPH Use Same Formula, Then Add 1 Second for the Additional Speed < 40 FOOT TRUCK = 4 SECONDS rinirnn < > 60 FOOT TRUCK (TRACTOR-TRAILER) = 7 SECONDS FIGURE 3-29: FORMULA FOR SAFE FOLLOWING DISTANCE Driving too fast is a major cause of fatal crashes.

Speed and Stopping Distance There are three things that add up to total stopping distance: 1. Perception Distance I 2. Reaction Distance 3. Braking Distance I / The total stopping distance may also be stated by the following formula: Perception Distance + Reaction Distance + Braking Distance = Total Stopping Distance o I 1 1 r i Perception Distance You sec a hazard and your brain knows 11 Reaction Distance You release accelerator anti apply the brakes Braking Distance How long It takes you to stop after you pul on brakes i 'I'lic total distance covered by the vehicle before you can brake to a full stop.

With air brakes, there is an added delay ^coming to a stop: the time it takes for the brakes to work after brake pedal is pushed. With hydraulic brakes (used on cars w ^d smaller trucks), the brakes work at once. However, with air Sbrakes, it takes a little time (up to half a second) for the air to flow ^ugh the lines to the brakes. Thus, the total stopping distance tfor vehicles with air brake systems is made up of four different !f&fl

The top knob is termed the System Parking Brake Valve, or parking brake, and is yellow. When pulled, the brakes will actuate for the entire unit.
