1 NIGHT DRIVING FAMILIARIZATION
2 PURPOSETO FAMILIARIZE DRIVER CANDIDATES WITH NIGHT DRIVING HAZARDS AND PROCEDURES.
3 REFERENCESAR , THE ARMY DRIVER AND OPERATOR STANDARDIZATION PROGRAMFM , MANUAL FOR THE WHEELED VEHICLE DRIVERTC , TRAINING PROGRAM FOR NIGHT VISION GOGGLE OPERATIONSTM AN/PVS-5 NIGHT VISION GOGGLES OPERATOR’S MANUALTM , AN/PVS-7A NIGHT VISION GOGGLES OPERATOR’S MANUAL
4 VISION BASICSLIGHT ENTERS THE EYE THROUGH THE PUPIL AND PASSES THROUGH THE LENS WHERE IT IS FOCUSED ON THE RETINADEPTH PERCEPTION: USED TO DETERMINE HEIGHT AND DISTANCEVISUAL ACUITY: HOW WELL YOU CAN SEE20/20 IS CONSIDERED NORMAL VISIONDARK ADAPTATION TAKES MINUTESMOVEMENT PLANNERS MUST CONSIDER THIS WHEN PLANNING NIGHT OPERATIONS
5 PHYSICAL FACTORS IMPACTING NIGHT VISION
SMOKING REDUCES NIGHT VISION ABILITY BY 20 PERCENTFATIGUE SLOWS YOUR RESPONSE AND IMPACTS JUDGEMENTEAT FOODS WITH VITAMIN A TO IMPROVE NIGHT VISION (EGGS, CARROTS, CHEESE)EXERCISE DAILY TO HELP PREVENT FATIGUEGET ENOUGH SLEEP BEFORE CONDUCTING NIGHT DRIVING OPERATIONS
6 INTRODUCTION TO NIGHT DRIVING
FATALITY RATE FOR NIGHTTIME DRIVERS IS TWICE THAT OF DAYTIME DRIVERSBASED ON MILES DRIVEN, NIGHT DRIVING IS TWO TO THREE TIMES MORE DANGEROUS THAN DAY DRIVINGFATIGUE AND REDUCED VISION ARE THE MAIN CAUSES OF THE GREATER DANGERDAYTIME: DRIVERS CAN SEE SEVERAL THOUSAND FEET AHEADNIGHTTIME: DRIVERS CAN ONLY SEE AT MOST A FEW HUNDRED FEET
7 HEADLIGHT GLARE CAN BLIND YOU FOR 2 -3 SECONDS
AT 50 MPH 3 SECONDS = 219 FEETFATIGUEIMPAIRS JUDGEMENTSLOWS REACTIONSMANY DRIVERS AT NIGHT ARE FATIGUEDMAY CAUSE OPTICAL ILLUSIONSINCREASES GLARE RECOVERY TIME
8 NIGHT DRIVING SAFETYSCAN FOR HAZARDS AS FAR AHEAD AS POSSIBLESPEED RULE OF THUMB: NEVER OUTRUN YOUR HEADLIGHTSYOUR STOPPING DISTANCE SHOULD BE LESS THAN YOUR SIGHT DISTANCEHEADLIGHTS MUST SHINE 200 FEETSTOPPING DISTANCE AT 55MPH = 307 FEET (107 FEET MORE THAN SIGHT DISTANCE)BOTTOM LINE: SLOW DOWN AT NIGHT
9 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
NVGs AMPLIFY AVAILABLE AMBIENT LIGHTSTARLIGHTMOONLIGHTOTHER SOURCESNVGs DO NOT MAGNIFY IMAGESPERFORMANCE DIRECTLY RELATED TO AMOUNT OF AMBIENT LIGHTMORE AMBIENT LIGHT MEANS BETTER RESOLUTION AND OBJECT IDENTIFICATIONDISCUSS WHAT HAPPENS IN A BLOWOUT:- A LOUD BANG- VEHICLE SWERVES FROM SIDE-TO SIDE- HARD TO STEER
10 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
VISUAL ACUITY WITH NVGs WILL ALWAYS BE LESS THAN NAKED EYESBEST ACUITY WITH AN/PVS-7 NVG = 20/40BEST ACUITY WITH AN/PVS-5 NVG = 20/50DEPTH PERCEPTION EFFECT:0-20 FEET: DEPTH PERCEPTION DECREASEDFEET: DEPTH PERCEPTION ABOUT EQUAL TO UNAIDED EYE500 FEET AND MORE: DEPTH PERCEPTION DECREASED
11 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
PERIPHERAL VISION REDUCEDNO COLOR DISCRIMINATIONNVG PICTURE IS GREENHARD TO DISTINGUISH BETWEEN SOME OBJECTSSOME EFFECTS MAY LINGER AFTER NVGs ARE REMOVEDRAIN, HAZE, FOG, SNOW AND SMOKE REDUCE NVG PERFORMANCE
12 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
THREE GENERATIONS OF NVGsAN/PVS-5 IS SECOND GENERATIONAN/PVS-7 MAY BE SECOND OR THIRD GENERATIONTHIRD GENERATION NVGs HAVE REDUCED SENSITIVITY TO BLUE OR GREEN LIGHTFOR NIGHT OPERATIONS USE FLASHLIGHTS WITH BLUE OR GREEN FILTERSSECOND GENERATION NVGs FAIL GRADUALLYMAINTENANCE PERSONNEL MUST CHECK THEM FREQUENTLY TO ENSURE PROPER OPERATION

13 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
USE OF NVGs DURING DAYLIGHT WILL DAMAGE THE NVGINFRARED LIGHT MAY BE USED BUT MAKES THE NVG AN ACTIVE SYSTEM THAT THE ENEMY CAN DETECTNVGs PROTECT YOUR EYES FROM LASERSUSE OF VEHICLE INSTRUMENT PANEL LIGHTS REDUCES NVD EFFECTIVENESSAVOID ROUGH HANDLING OF NVGs
14 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
CARE AND MAINTENANCEPROTECT NVGs FROM DUST, SAND, AND HUMIDITYDO NOT USE ANTI-MISTING CLOTHS OR CHEMICALS ON THE LENSESUSE LENS COVERS WHEN NOT WEARING THE GOGGLESENSURE THE SELECTOR IS IN THE OFF POSITION BEFORE INSTALLING OR REMOVING BATTERIES
15 NIGHT VISION GOGGLE (NVG) FAMILIARIZATION
CARE AND MAINTENANCE (CONTINUED)NVG RESOLUTION CHECKS ARE REQUIRED EVERY 180 DAYSCHECK FOR PROPER TUBE OPERATION BEFORE EACH MISSIONNEVER STORE NVGs WET OR IN A WET CARRYING CASEREAD THE TM TO ENSURE YOU FULLY UNDERSTAND PROPER OPERATING AND MAINTENANCE PROCEDURES

16 DRIVING WITH NIGHT VISION GOGGLES
FOR MOST EFFECTIVE NVG OPERATION, DIM OR TAPE OVER ALL VEHICLE DASHBOARD LIGHTSNO DARK ADAPTATION PERIOD NEEDED FOR NVG USEKEEP ANY BRIGHT LIGHTS OUT OF THE NVG FIELD OF VIEWREMEMBER DUST, RAIN, FOG AND SNOW REDUCE NVG EFFECTIVENESS
17 DRIVING WITH NIGHT VISION GOGGLES
SPEED RULE OF THUMB: NEVER DRIVE FASTER THAN 25 MPH WITH NVGsAR , CHAPTER 8, REQUIRES COMMANDERS TO ESTABLISH NVG SPEED LIMITS BASED ON:TYPE AND GENERATION OF NVGTYPE OF VEHICLES BEING DRIVENWEATHERTERRAINMISSION/ROUTE TYPEAMOUNT OF LIGHT AVAILABLE
18 DRIVING WITH NIGHT VISION GOGGLES
FM , CHAPTER 23 HAS GRAPHS NEEDED TO DETERMINE SAFE SPEED UNDER DIFFERENT CONDITIONSNEVER USE NVGs ON PUBLIC ROADS OR HIGHWAYSUSE A CONTINUAL, SLOW SCANNING PATTERN TO IMPROVE OBJECT IDENTIFICATIONUSE GROUND GUIDES WHEN OPERATING A VEHICLE WHILE USING NVGsIF THE VEHICLE OR NVGs MALFUNCTION WHILE DRIVING, PULL TO THE RIGHT HAND SIDE OF THE ROAD AND WARN OTHER DRIVERS

20 REAR BLACKOUT MARKER LIGHTS
EACH REAR LAMP HAS 2 PAIRS OF “CAT’S EYES”TURNS RED WHEN ONONE LIGHT: TOO FAR AWAYTWO LIGHTS: JUST RIGHTFOUR LIGHTS: TOO CLOSEBLACKOUT STOP-LIGHT FLASHES WHITE WHEN BRAKES ARE APPLIED
21 FRONT BLACKOUT MARKER LIGHTS
EACH FRONT LIGHT HAS ONE PAIR OF CAT’S EYESTURNS WHITE WHEN ONMORE THAN 60 FEET AWAY: EACH PAIR APPEARS AS ONE LIGHTLESS THAN 60 FEET AWAY: APPEARS AS A PAIR OF CAT’S EYES IN EACH LIGHT
