Make sure you are in a low enough gear, usually lower than the gear required to climb the same hill. Before Entering a Curve. Slow down to a safe speed, and downshift to the right gear be- fore entering the curve. This lets you use some power through the curve to help the vehicle be more stable while turning. It also allows you to speed up as soon as you are out of the curve.

Wet ice is much more slippery than ice that is not wet. • Black Ice. Black ice is a thin layer that is clear enough that you can see the road underneath it. It makes the road look wet. Any time the temperature is below freezing and the road looks wet, watch out for black ice. • Vehicle Icing. An easy way to check for ice is to open the window and feel the front of the mirror, mirror support, or antenna. If there’s ice on these, the road surface is prob- ably starting to ice up. • Just After Rain Begins. Right after it starts to rain, the water mixes with oil left on the road by vehicles. This makes the road very slippery. If the rain continues, it will wash the oil away. • Hydroplaning. In some weather, water or slush collects on the road. When this hap- pens, your vehicle can hydroplane. It’s like water skiing--the tires lose their contact with the road and have little or no traction. You may not be able to steer or brake. You can regain control by releasing the accelerator and pushing in the clutch. This will slow your vehicle and let the wheels turn freely. If the vehicle is hydroplaning, do not use the brakes to slow down. If the drive wheels start to skid, push in the clutch to let them turn freely. It does not take a lot of water to cause hydro- planing. Hydroplaning can occur at speeds as low as 30 mph if there is a lot of water. Hydro- planing is more likely if tire pressure is low, or the tread is worn. (The grooves in a tire carry Figure 2.11 away the water; if they aren’t deep, they don’t work well.)

• In bad weather. Many car drivers follow large vehicles closely during bad weather, espe- cially when it is hard to see the road ahead. If you find yourself being tailgated, here are some things you can do to reduce the chances of a crash. • Avoid quick changes. If you have to slow down or turn, signal early, and reduce speed very gradually. • Increase your following distance. Opening up room in front of you will help you to avoid having to make sudden speed or direction changes. It also makes it easier for the tail- gater to get around you. • Don’t speed up. It’s safer to be tailgated at a Figure 2.13 low speed than a high speed. • Avoid tricks. Don’t turn on your taillights Figure 2.14 or flash your brake lights. Follow the sug- gestions above.

EFFECTS OF INCREASING BLOOD ALCOHOL CONTENT (BAC) 2.22 – Alcohol, Other Blood Alcohol Content is the amount of alcohol in your blood recorded in milligrams of Drugs, and Driving alcohol per 100 milliliters of blood. Your BAC depends on the amount of blood (which increases with weight) and the amount of alcohol you consume over time (how fast you 2.22.1 – Alcohol and Driving drink). The faster you drink, the higher your BAC, as the liver can only handle about one drink per hour—the rest builds up in your blood.

Identification Numbers are a four digit code used by first responders to identify hazard- ous materials. An identification number may be used to identify more than one chemical on shipping papers. The identification number will be preceded by the letters “NA” or “UN.” The US DOT Emergency Response Guidebook (ERG) lists the chemicals and the identification numbers assigned to them. Not all vehicles carrying hazardous materials need to have placards. The rules about placards are given in Section 9 of this manual. You can drive a vehicle that carries hazardous materi- als if it does not require placards. If it requires placards, you cannot drive it unless your driver license has the hazardous materials endorse- ment. See Figure 2.25. The rules require all drivers of placarded ve- hicles to learn how to safely load and transport hazardous products. They must have a commer- cial driver license with the hazardous materials endorsement. To get the required endorsement, you must pass a written test on material found in Section 9 of this manual. A tank endorsement is required for certain vehicles that transport liquids or gases. The liquid or gas does not have to be a hazardous material. A tank endorsement is only required if your vehicle needs a Class A or B CDL and your vehicle has a permanently mounted cargo tank of any capacity; or your vehicle is carrying a portable tank with a capac- ity of 1,000 gallons or more. Drivers who need the hazardous materials endorsement must learn the placard rules. If you do not know if your vehicle needs placards, ask your employer. Never drive a vehicle needing placards unless you have the hazardous mate- rials endorsement. To do so is a crime. When stopped, you will be cited and you will not be allowed to drive your truck. It will cost you time and money. A failure to placard when needed may risk your life and others if you have an ac- cident. Emergency help will not know of your hazardous cargo. Hazardous materials drivers must also know which products they can load together, and which they cannot. These rules are also in Section 9. Before loading a truck with more than one type of product, you must know if it is safe to load them together. If you do not know, ask your employer and consult the regulations. Figure 2.25

This rating is information you need to pass the hazardous stated on the side of each tire. 3.2.3 – Don’t Be Top-heavy materials test. The height of the vehicle’s center of gravity is very important for safe handling. A high center of gravity (cargo piled up high or heavy cargo on top) means you are more likely to tip over. It is most dangerous in curves, or if you have to swerve to avoid a hazard. It is very important to distribute the cargo so it is as low as possible. Put the heavi- est parts of the cargo under the lightest parts.

3.2.4 – Balance the Weight Poor weight balance can make vehicle han- dling unsafe. Too much weight on the steering axle can cause hard steering. It can damage the steering axle and tires. Under-loaded front axles (caused by shifting weight too far to the rear) can make the steering axle weight too light to steer safely. Too little weight on the driving axles can cause poor traction. The drive wheels may spin easily. During bad weather, the truck may not be able to keep going. Weight that is loaded so there is a high center of gravity causes greater

The air brake lag distance at 55 mph on dry pavement adds about 32 feet. So at 55 mph for an average driver under good traction and brake conditions, the total stopping distance is over 450 feet. See Figure 5.6.

5.4.5 – Brake Fading or Failure Brakes are designed so brake shoes or pads rub against the brake drum or disks to slow the vehicle. Braking creates heat, but brakes are designed to take a lot of heat. However, brakes can fade or fail from excessive heat caused by using them too much and not relying on the engine braking effect. Excessive use of the service brakes results in overheating and leads to brake fade. Brake fade results from excessive heat causing chemical changes in the brake lining, which reduce fric- tion, and also causing expansion of the brake drums. As the overheated drums expand, the brake shoes and linings have to move farther to contact the drums, and the force of this contact is reduced. Continued overuse may increase brake fade until the vehicle cannot be slowed down or stopped. Brake fade is also affected by adjustment. To safely control a vehicle, every brake must do its share of the work. Brakes out of adjustment will stop doing their share before those that are in adjustment. The other brakes can then overheat and fade, and there will not be enough braking available to control the vehicle(s). Brakes can Figure 5.6 get out of adjustment quickly, especially when they are hot. Therefore, check brake adjustment often. the spring brakes do not work on all axles.

• Recognize the Skid. The earliest and best TRAILER JACKNIFE way to recognize that the trailer has started to OFF TRACKING IN A skid is by seeing it in your mirrors. Any time 90 DEGREE TURN you apply the brakes hard, check the mirrors to make sure the trailer is staying where it should be. Once the trailer swings out of your lane, it’s very difficult to prevent a jackknife. • Stop Using the Brake. Release the brakes to get traction back. Do not use the trailer hand brake (if you have one) to “straighten out the rig.” This is the wrong thing to do since the brakes on the trailer wheels caused the skid in the first place. Once the trailer wheels grip the road again, the trailer will start to follow the tractor and straighten out. * (From R.D. Ervin, R.L. Nisconger, C.C. Figure 6.3 MacAdam, and P.S. Fancher, “Influence of size and weigh variables on the stability and control properties of heavy trucks, “University of Mich- igan Transportation Research Institute, 1983).

6.1.6 – Turn Wide When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called offtracking or “cheating.” Figure 6.3 shows how offtracking causes the path followed by a tractor to be wider than the rig itself. Longer vehicles will offtrack more. The rear wheels of the powered unit (truck or tractor) will offtrack some, and the rear wheels of the trailer will offtrack even more. If there Figure 6.2 is more than one trailer, the rear wheels of the Figure 6.4 last trailer will offtrack the most.

Rolling Over To prevent trailers from rolling over, you must steer gently and go slowly around corners, on ramps, off ramps, and curves. A safe speed on a curve for a straight truck or a single trailer combination vehicle may be too fast for a set of doubles or triples.

7.1.2 – Beware of the Crack-the-whip Effect Doubles and triples are more likely to turn over than other combination vehicles because of the “crack-the-whip” effect. You must steer gently when pulling trailers. The last trailer in a combination is most likely to turn over. If you don’t understand the crack-the-whip effect, study subsection 6.1.2 of this manual.
