By following the foregoing instructions closely, you will make clear fingerprints which can be classified quickly and accurately. In police work, it is often important that fingerprints be classified quickly for purposes of identification. However, identification cannot be made quickly if the quality of the prints is unsatisfactory. Make the prints right the first time!

CHAPTER 4

MOTOR PATROL AND BEACH GUARD

In addition to the foot patrol, many shore patrol organizations operate motor patrols, sometimes called cruiser patrols. The motor patrol is very effective for covering outlying areas beyond the beats of the foot patrol, for giving extra coverage in districts popular with liberty parties, for transporting reinforcements rapidly, for removing prisoners, and for inspecting foot patrols. Ordinary practice is to keep several vehicles patrolling, while others are held at headquarters for emergency use. The crew of a motor patrol vehicle usually consists of two men. If possible do not leave the vehicle unattended at any time while on patrol. In any case do not leave the key in the ignition switch. There have been a number of instances where motor vehicles were stolen, ignition wires were cut, or other damage was done. For example, one vehicle parked on an incline was wrecked when the hand brake was released by a malefactor.

MOTOR PATROL

The motor patrol is ideal for supervising the foot patrol and for lending speedy assistance in case of trouble. This patrol shall view as many of the foot patrolmen on their rounds as possible, and shall make careful note of the manner in which they are carrying out their duties.

Traffic Rules

Before operating a shore patrol vehicle, you must receive authority from the shore patrol officer. You must

be familiar with the local traffic code and be thoroughly acquainted with the district to which you are assigned. The following safe driving precautions should be practiced:

1. When you are approaching a corner and another car is crossing your path at a rapid rate, let it cross ahead of you, even if you have the rightof-way.

2. Make all required hand signals promptly, properly, and distinctly.

3. When the driver ahead of you makes an indistinct hand signal, slow down, or stop, until you have determined what he proposes to do.

4. Pass parked cars carefully, especially in school zones. When the street is clear, drive at a moderate, safe speed.

5. Stop for school buses when they are loading or unloading.

6. Never drive while under the influence of alcoholic

beverages.

7. If you meet a car that is weaving or hugging the

center line of the highway, slow down and move to your right. Don't try to force the driver of the other car back to his lane by hugging the center line yourself.

8. Never pass a car near the top of hill, on a curve, or at any place where your view of the highway is obstructed.

9. Leave enough space between your vehicle and the car ahead, since this space may give you time to stop without colliding.

10. At night dim your lights for approaching vehicles and reduce your speed, so that you will always have a clear view of the highway ahead.

11. Reduce your speed in rain, sleet, snow, fog, or other conditions that limit visibility, thus allowing adequate time for sudden stops.

12. Never exceed legal speed limits, and don't drive

over 50 miles per hour at any time. The little time gained by fast driving is not worth the price paid for decreased safety and wear and tear on the vehicle.

13. When starting to move on a slippery pavement, put the car in second gear and accelerate gently. 14. Keep your mind on your business and your car under control at all times.

The Uniform Vehicle Code states that at a speed of 20 miles per hour brakes must be applied at least 30 feet ahead of the stopping point. At 40 miles per hour the stopping distance increases to from 80 to 100 feet. This distance makes allowance for skidding with all four wheels stopped.

Tests show that better mileage per gallon of gasoline is obtained at speeds ranging from 25 to 35 miles per hour. Air resistance increases enormously as velocity increases. It varies greatly, depending on the shape of the moving body. Streamlining is an attempt to reduce the effect of air resistance. Conserve gasoline and equipment when stopping at a red light by coasting to the stopping point and using your brakes as little as necessary.

Care of Vehicle

If you are assigned as the driver of a shore patrol vehicle, you have certain responsibilities for the upkeep of the vehicle other than its safe operation.

Before you start a patrol inspect your vehicle. Be sure you have the tank filled with fuel, sufficient oil in the crankcase, adequate water and antifreeze in the radiator, correct air pressure in the tires, and a fully-charged battery. Test the windshield wiper, lights, horn and siren, to make sure they are all in operating condition. When hauling materials, check the vehicle for proper loading.

You are expected to take good care of the vehicle while operating it. Don't ride the clutch, avoid excessive idling,

keep the choke pushed in after the engine is warm, and shift the gears smoothly.

If you are involved in an accident, report it immediately. Make sure your vehicle carries copies of Operator's Report of Motor Accident (Standard Form 91). Fill out the form completely.

Always park your vehicle properly, and, if a special parking space is assigned, park in that space. NEVER LEAVE KEYS IN AN UNATTENDED CAR. Use your siren only during an emergency, and according to rules prescribed by the shore patrol officer. Never permit unauthorized persons to operate (or to ride as passengers in) a vehicle assigned to you. Keep your vehicle clean and smart at all times.

Maintenance personnel should use the Automotive Preventive Maintenance Manual (NavDocks P-6) as a guide, and they should carry out the preventive-maintenance program described therein.

Be sure all required work is carried out as scheduled, since proper maintenance will hold vehicle failures to a minimum. The more important phases of the maintenance schedule should be carried out as follows:

1. WEEKLY.-Check tires, batteries, and other points indicated on NavDocks Form 1187. Tires must have proper air pressure when cold, since pressures increase as tires are driven over the road. Make sure all valve caps are replaced after tires are checked. Batteries must have sufficient water, clean and tight cable terminals, and a proper charge, as indicated by the hydrometer.

2. SEMI-YEARLY.-Every six months, or at the end of 6,000 miles (whichever occurs first), a complete servicing shall be carried out in accordance with NavDocks Form 1076. Follow the lubrication chart carefully, and check mileages closely for periodic lubrication. Remember that lubrication requirements differ with different types of vehicles, and that all withdrawals of gasoline and lubricating oil must be logged on NavDocks Form 1073, signed by the vehicle operator.
