Work zones
Flashing arrow boards mark lane closures or crossovers, with markings, cones, barrels or barricades outlining the path; a board flashing with no direction means caution without a lane change. You must stop when a flagger holds a fluorescent orange or red flag horizontally into traffic and may proceed slowly only when directed; with a paddle, obey STOP or SLOW; automated flagger devices show the same messages or red and yellow lights. Stay alert for lower limits, narrow lanes and workers; read the signs; merge early unless signs call for late or zipper merging toward the closure; slow down; do not tailgate; minimize distractions; expect delays; and consider alternate routes.
Railroad crossings
Not every crossing has every device. Vehicles carrying passengers for hire, school buses, and vehicles carrying explosives or flammable liquids must always stop no closer than 15 feet and no farther than 50 feet from the nearest rail, except at signed abandoned tracks. A crossbuck alone works as a yield sign: you decide whether to stop, but you must stop for an approaching train; with a stop sign, stop completely and cross only after making sure no train is coming; with active bells, lights or gates, stop and wait until the warning ends or an officer or railroad flagman waves you on. Never drive around a lowered gate, never race a train (its speed is deceiving), never stop or shift gears on the tracks, never start across unless you can clear without stopping, and if your vehicle stalls, get everyone out at once. Watch for a second train behind or beyond the first, expect quiet zones where trains do not sound horns at some gated crossings, treat signals flashing red in all directions on streets with tracks as a crossing warning, and never pass within 100 feet of a crossing. Once the lights flash and the gate starts down you have about 20 seconds; if a vehicle is stuck with a train coming, evacuate and run at a 45-degree angle away from the tracks toward the train, then call 911. With no train coming, call the Emergency Notification System number on the blue sign at the crossing with the obstruction and location, then 911.
Tractor-trailers
Without a special permit a vehicle may be no wider than 8 feet 6 inches, no taller than 13 feet 6 inches and no heavier than 80,000 pounds, and trucks or buses 80 inches or wider need extra marker lights. A car at 55 mph stops in about 130 to 140 feet, half a football field, while a loaded tractor-trailer with hot brakes may need more than 400 feet, so never change lanes or stop suddenly in front of one. Rear wheels follow a shorter path, so trucks swing out to start tight turns; watch the signals before passing, especially on the right. Blind spots reach up to 20 feet in front of the cab, along both sides of the cab and trailer, and up to 200 feet behind. Trucks keep to the center lane on multilane highways to let local traffic on and off and to leave escape options. Never cut off a truck to reach an exit or a single-lane work zone, never linger alongside (pass completely and always on the left), never tailgate (if you cannot see the driver's mirrors the driver cannot see you), and never underestimate a truck's size and speed at intersections.
The Move Over law and school buses
Indiana's Move Over law requires you to yield, move right and stop, or change lanes when approaching an emergency vehicle with flashing lights. For an emergency vehicle showing red, red and white, or red and blue lights (fire, police, ambulances, hospital and EMS vehicles, INDOT- designated vehicles and corrections vehicles on emergencies), change lanes away from it or, if you cannot, slow to 10 mph under the limit and proceed with caution; failing is a Class A infraction. For an authorized parked vehicle with amber lights (tow trucks, highway maintenance, utility, trash and survey or construction vehicles) and for a disabled vehicle with hazard flashers, the same duty applies and failing is a Class B infraction. School buses flash amber to warn they are about to stop and red with the stop arm once stopped; you must stop for red lights and an extended arm, except that on a road divided by a barrier or unimproved median you stop only when traveling the bus's direction. Children approaching or leaving the bus are at greatest risk, so watch for them at stops and prepare to stop when the amber lights appear. Passing a stop arm is a Class A misdemeanor, a Level 6 felony with bodily injury and a Level 5 felony with a death. School buses stop at railroad crossings, and rear-end crashes there have increased.
Motorcycles, bicycles, slow vehicles and officers
Motorcyclists and motor driven cycle riders get the full width of a lane; their small profile makes speed and distance hard to judge, they stop faster than cars, they hide in blind spots, and their signals usually do not cancel, so wait until a rider acts before proceeding. Potholes, gravel, wet pavement, seams, crossings and grooved pavement can force sudden moves; follow at least three or four seconds. Bicyclists have the rights and duties of other users: pass with at least three feet and no oncoming danger, yield to them as to any vehicle, expect no more than two abreast, remember they may use the travel lane instead of a bike lane, never turn across a bicyclist's path, wait for an oncoming bicyclist before turning left, stay behind a bicyclist sharing a left-turn lane, let a bicyclist on your right through before turning right, and check for bicyclists before opening a door. Bicycle paths and lanes are for bicycles only unless signed for pedestrians or used by on-duty workers such as mail carriers: do not drive or park in them or block them, yield to bicyclists in them, do not move into them to prepare for a turn, and cross them only when turning or entering or leaving an alley, driveway or private road. Sharrows (a bike with two arrows) position cyclists away from parked cars and warn drivers to expect them; green pavement highlights bike lanes and red pavement bus or transit lanes. Farm equipment, construction machinery and animal-drawn vehicles carry the slow-moving emblem, and horse riders and drivers have full road rights, so approach with caution and watch for their hand signals. An officer directing traffic overrides signals and signs, and official processions such as funerals have the right-of-way regardless of signals.
Parking, reversing and pedestrians
To parallel park, signal, stop parallel to the front car at least two feet away with rear bumpers aligned, reverse until your front is even with its front door, turn sharply right to about 45 degrees, turn sharply left as your front passes its rear, then straighten and pull forward. Facing downhill, turn the wheels toward the curb; facing uphill, away from the curb; with no curb, away from the street. Signal when leaving a space and double-check both ways when backing out. To reverse, turn your body right to look through the back window, never relying on the mirror alone, go slowly, and never back into an intersection to turn around. Do not park on highways unless allowed, in intersections or crosswalks, on sidewalks or before driveways, within 15 feet of a hydrant or in fire lanes, on bridges or in tunnels, beside yellow curbs, beside another parked vehicle, in accessible spaces without a valid placard, or in the diagonally striped area beside them, which is off limits even with a placard because wheelchair users need it for ramps and transfers. Always yield to pedestrians, never make a turn that forces a pedestrian to stop, slow or dodge, take special care with children and with elderly or visually impaired people, and always yield to anyone with a white cane or guide dog; everyone is a pedestrian.
Seat belts, child restraints and truck equipment
Belts raise front-seat survival odds 45 percent and cut serious injury 50 percent; Indiana requires the driver and every passenger, and bus operators, to be belted whenever the vehicle operates, even with air bags, which are built to work with belts. Wear the belt low on the hips and flat across the collarbone, sit at least 12 inches from the wheel, and set head restraints above the top of and close to the head. Exemptions include documented medical reasons, children in child restraints, frequent-stop delivery and postal vehicles, rural mail and newspaper carriers, BMV examiners on tests, farm trucks on farms, parade vehicles, RV living quarters, ambulance treatment areas, sleeper berths, and non-driver occupants of waste trucks, construction-site trucks, tow-truck cabs and utility emergency vehicles. Children under eight must ride in a child car seat or booster. Air bags have killed children and adults under five feet tall, so the National Safety Council recommends the back seat for children under 12. Trucks and buses need two red tail lamps, a white plate lamp and a red stop lamp, plus a working four-way hazard flasher; loads extending more than four feet beyond the rear carry a red lamp visible 500 feet from the sides and rear between sunset and sunrise and a red flag of at least 12 square inches by day. A disabled car with headlights required on a divided highway sets a lighted fuse, red lantern or red reflector 100 feet behind and 100 feet ahead in its lane plus one on the traffic side about 10 feet away toward approaching traffic; by day, two red flags 100 feet ahead and behind; within 500 feet of a curve, hilltop or obstruction, a device at least 500 feet away. A disabled truck, bus or tractor-trailer displays three bidirectional reflective triangles, six fuses or three liquid-burning flares: one on the traffic side, one 100 feet toward traffic, one 100 feet the other way, 200 feet on a divided highway, and 500 feet near a curve or crest; when headlights are not needed, triangles or red flags replace flares and no traffic-side flare is required.
