Safe Passing of Two-Wheeled Vehicles.

Motorcycles and bicycles are lighter and more subject to wind effects than 4-wheeled vehicles are. Due to this, special care must be taken when passing. a. Aerodynamic effects around a large vehicle can cause a two-wheeled vehicle to be suddenly pulled toward the larger vehicle by two or three feet, depending on the relative speed between the two vehicles. You should always allow at least six feet to the left of the two-wheeled vehicle when you are passing. b. When passing a two-wheeled vehicle, do not attempt to share the lane with that vehicle. Move into the next or oncoming lane to pass. If there is oncoming traffic, then slow and follow the two- wheeled vehicle until oncoming traffic clears.

True

Section 2.7 and 2.8 How do you find out how many seconds of following distance space you have?

- If you are driving a 40 ft. truck and only counted up to 2 seconds, you're too close. Drop back a little and count again until you have 4 seconds of following distance. (or 5 seconds, if you're going over 40 mph.) - to know how much space you have wait until the vehicle ahead passes a shadow on the road, a pavement marking, or some other clear landmark. Then count off the seconds like this: "one thousand-and one, one thousand-and-two" and so on, until you reach the same spot.

Section 14 Safe Backing Practices.

A large or long vehicle is much more difficult to back safely than a smaller one. These practices are recommended. a. When you must back, get out and walk around your truck and make certain there is nothing behind. Then back immediately and watch carefully. b. Use both rearview mirrors. You can't see the right side while hanging out the left door. c. If necessary to back some distance, stop part way, then get out and check your progress. d. Try to have someone standing in a safe place to guide you by signaling. e. Park where you will not have to back to get away from the parking place. f. Never back around an intersection corner to turn around. g. If you have to back in or out of a driveway, where possible, back into the driveway from the street so that you can drive out forward and see where you are going. h. When backing over a sidewalk into a street, stop at the sidewalk to make especially certain that there is no child playing behind or close by. Stop again at the curb to make a last check on traffic before backing into the street. i. Don't depend entirely upon your rear vision mirror.

Section 14 Papers

All commercial motor vehicles, truck tractors, trail- ers, or semitrailers must carry registration papers (receipt for license plates) on the vehicles while operating on a public highway. These papers shall show the weight of the vehicle empty and how much it is registered to haul.

Section 14 Turn Signal Indicators.

All motor vehicles, trailers, semitrailers, or pole trailers except motorcycles and certain trailers shall be equipped with electrical turn signal lights, except that passenger cars or trucks under 80 inches in width and manufactured prior to the year model 1960 need not be equipped with electrical turn signals unless the body or load of the vehicle or combination of vehicles extends to side more than 24 inches from the center of the top of the steering wheel, or the rear limit of the body or load exceeds more than 14 feet from the center of the top of the steering wheel.

Section 14 Fire Extinguisher

All school buses, buses, taxis, and other vehicles hauling passengers for hire or lease, must carry a chemical type fire extinguisher of at least one quart capacity. Commercial vehicles that are subject to the Federal Motor Carrier Safety Regulations must be equipped with a fire extinguisher that is properly filled and located so that it is readily accessible for use. The fire extinguisher must be securely mounted on the vehicle. (Note: Extinguishers, when required, must meet the standards of 393.95 of the Code of Federal Regulations.)

Section 14 Mud Flaps.

All trucks and trailers with four or more tires on the rear axle must be equipped with safety guards or mud flaps behind the rear wheels.

Subsection 2.15-2.16 Describe the proper braking technique when going down a long steep downgrade

Apply the brakes just hard enough to feel a definite slowdown.

Speeding

Speeding by trucks is a common cause of accidents and another major complaint by motorists. Driving too fast for conditions - regardless of the posted speed - is dangerous. Remember, obeying the speed limit: J Saves lives, injuries, and property damage.J Increases fuel economy by as much as a mile per gal- lon at 55 mph rather than 65 mph. J Saves wear and tear on tires, brakes, and engines. J Allows sufficient time and space to stop after a hazard is sighted. Remember, you stopping distance increases at a much faster rate than your speed. If you double your speed, your stopping distance will be four times greater.

Subsection 5.2- 5.3 How can you test that the spring brakes come on automatically?

Step on and off the brake, with the engine off, the parking brake knob should pop out when air pressure falls between 20-40 psi.

Hot and Cold

Summer driving has its own perils. Truck drivers should especialy be on the lookout for: J Lost, fatigued motorists on vacation who may sudden- ly stop, or swerve across several lanes of traffic to an exit. J Overloaded cars with poor visibility and/or drivers dis- tracted by kids and pets. Highway construction projects where roads suddenly turn into narrow lanes with confusing signs. Heavy equipment and pedestrians are often nearby. J Winter ice and snow mean gearing down on grades to avoid wheel-spinning and brake lock-up which can lead to jackknifing. If you find a traffic jam-up and mul- tiple vehicle accidents, stay back and wait for them to clear before trying to get your rig through.

Tailgating

Tailgating is the most common complaint car drivers have against truck drivers. It may not always be justified, but it is a frequent one. The professional: -Keeps a gap between his or her truck and the car ahead in heavy traffic because the truck needs more space to stop. Remember, your truck looms frighteningly large in the mirror. - Maintains a four-second following distance on the open road. - Increases the distance of the gap to 6-8 seconds in bad weather (more reaction time) to compensate for poor traction and actions of less experienced car drivers. - Remains alert to the driver who cut into the open space in front of the truck. - Knows that tailgating or forming convoys promotes unsafe passes by groups of cars stacked up behind. If they do attempt to pass and don't make it, you and others could be involved in a serious accident.

Subsection 3.1-3.4 What must you check before transporting a sealed load?

That you don't exceed gross weight and axle weight

Section 14 SPECIAL REQUIREMENTS FEDERAL REGULATIONS

The Texas Department of Public Safety has adopted by ref- erence the Federal Motor Carrier Safety Regulations, 49 Code of Federal Regulations, Parts 390-393 and 395-397. The Department has also adopted the Federal Hazardous Materials Regulations, Parts 171-173, 177, and 178. For detailed information concerning these regulations adopted by the Department of Public Safety, see Rule §3.59 and Rule §3.62 which are on file with the Texas Secretary of State.

Passing

The following are basic reminders truck drivers should follow when passing and dealing with slower traffic: - Signals alone aren't enough. Before making a move, the professional truck driver makes sure that a lane change or passing maneuver can be made safely and without interfering with others. - Don't alarm a car driver by overtaking too closely before moving into the passing lane. Leave some extra space before you pull back in. - Rememberthatatruckpushesawallofairaheadofit. To avoid buffeting cars, keep as much space as pos- sible between the vehicles you pass. - Slow traffic and congestion are facts of life to the pro- fessional truck driver. Keep cool and lay off the horn and flashing of the headlights.

School Buses, Recreational Vehicles, and Others

The professional truck driver should be especially watchful for drivers of school buses, recreational vehicles, and driv- ers of rental trucks. These groups of drivers' levels of expe- rience vary a great deal. Therefore, truck drivers should: Give school buses as much room as possible. Watch for frequent stops to load and un-load children. Remember, the driver can be distracted by the chil- dren on the bus. Realize drivers of RV's and smaller vehicles pulling trailers can be a problem because they may not have the professional skills or knowledge of the profession- al truck driver. These vehicles are epecially suscepti- ble to turbulence from big trucks, so reduce your speed and give them plenty of room. Pass these vehi- cles with care and as far to the left as safely possible.

Section 14 Brakes

a. Trailers, semitrailers, and pole trailers with a gross weight of 4,500 pounds or less are exempt from brake requirements. Trailers, semitrailers, and pole trailers with a gross weight in excess of 4,500 pounds and which do not exceed 15,000 pounds and operated at speeds of 30 miles per hour or less are not required to be equipped with brakes. Trailers, semitrailers, and pole trailers with a gross weight in excess of 4,500 pounds and which do not exceed 15,000 pounds and are operated at speeds in excess of 30 miles per hour must have brakes acting on both wheels of the rear axle. b. Every motor vehicle, trailer, semitrailer, pole trail- er, and combination of such vehicles equipped with brakes shall have the braking system so arranged that one control device can be used to operate all brakes. This does not prevent the use of additional control devices to operate brakes on the towed vehicles. Surge or inertia brake systems may be used on trailers and semitrailers with a gross weight of 15,000 pounds or less. c. Under all conditions, the combination of vehicles must be capable of complying with the performance requirements. Generally, if the trailer and the combination is 3,000 pounds or less, the combination must be able to stop within 40 feet when traveling 20 miles per hour; if the trailer and the combination is in excess of 3,000 pounds, the combination must be able to stop within 50 feet when traveling 20 miles per hour
