1. lesson 11.4 TRUCKS, BUSES, AND EMERGENCY AND SPECIALIZED VEHICLES
When you share the roadway with larger vehicles, you must understand and respect their needs. It may be easy to see trucks and buses, but they present greater risks than smaller vehicles.

2. Identify the risks associated with sharing the road with large vehicles.
OBJECTIVE

3. Sharing the Road with Trucks
Service trucks, pickup trucks, and delivery trucks are usually light or medium-weight. Heavy trucks include dump trucks and tractor trailers.

4. A truck that has a powerful tractor pulling a separate trailer is called a tractor trailer.
The tractor includes the engine and driver’s cab.
The most common tractor trailer is the semi-trailer, which has one trailer.

5. In a collision, the sheer size of a heavy truck puts a car at risk.
Heavy trucks require long stopping distances. The metal bumpers are high and rigid.

6. Tractor trailers are much heavier than cars.
Which will have the greater stopping distance, the truck or the car behind the truck?

7. Describe how to follow, pass, and meet large trucks safely.
OBJECTIVE

8. The No Zone
Drivers of heavy trucks have very large blind spots—areas around the truck where your car can disappear from their view.
These blind spots are called the no zone.

9. The no zone includes areas at the side, rear, and front.
The front no zone can extend more than 20 feet.
Truck drivers have four large blind spots. If you are in a truck’s no zone, the driver cannot see you.
Why do you think one side of the truck has a larger no zone than the other?

10. If you can’t see the truck driver in the truck’s mirror, the truck driver can’t see you.
The right-side blind spot is the most dangerous because trucks make wide right turns.

11. Following Large Trucks
When you follow a large truck, it causes a line-of-sight restriction because you cannot see what’s ahead of the truck.

12. Trucks Making Right Turns
When following large trucks, be aware that they require plenty of space to make a turn.
In order to turn right, a truck usually starts by swinging out to the left.
To avoid conflict, keep out of the open space to the right of a tractor trailer that is making a right turn. Can the truck driver see the car?

13. Passing and Being Passed
Why is it safer to pass trucks that are going uphill than trucks that are going downhill?

14. To safely pass a long vehicle, you need more distance
To safely pass a long vehicle, you need more distance. When you are in position to pass, check your front and rear zones and your blind spots. Then signal a lane change.
Stay in lane position 2 and complete your pass carefully and quickly. Don’t linger in the no zone.
Signal and return to your lane only after you can see at least one headlight in your rearview mirror. Don’t slow down!

15. Be prepared for increased wind turbulence when passing a truck, or when a truck passes you.
Grip the steering wheel firmly.
Move to lane position 3 if conditions permit.

16. If you pass during rain or snow or when the road is wet, spray from the truck may cover your windshield.
Increase your wiper speed and use your windshield washer to keep your windshield clear.
If necessary, pull over in a safe location and clean your windows.

17. Meeting a Large Truck
You do not have much room when meeting large trucks on narrow, two-lane roads.

18. Before you commit to passing or turning left, check your gap and decide how quickly the vehicle is approaching.
Large vehicles often appear to be moving more slowly than they really are.

19. Buses Buses have large no zones and take extra space to turn.
They also cause line-of-sight restrictions.

20. Did You Know?
Radio Reporting Some states outfit school bus drivers with radio communicators so they can report violating drivers immediately. Drivers are more likely to be apprehended and suffer immediate consequences for putting children’s lives at risk.

21. Public Buses
Local transportation buses make frequent stops to pick up and drop off passengers, usually at intersections. Some communities provide special bus lanes to help move traffic.

22. Describe the precautions you must take when driving near school buses and emergency vehicles.
OBJECTIVE

23. School Buses
As a driver, you have the responsibility for driving cautiously near school buses.
Watch for bright yellow buses in the morning and afternoon when schools are opening and closing.

24. Reduce speed around school bus stops.
Children are at greatest risk of injury around buses that are loading or unloading.
Reduce speed around school bus stops.
Search for children who are rushing to catch a bus. Be prepared to stop.

25. When the red lights on a school bus are flashing, you must stop.
Some school buses have amber lights that flash before the red lights begin, or a STOP arm that swings out from the driver’s side of the bus.

26. When the red lights begin to flash, motorists traveling in both directions must stop before reaching the school bus.
All traffic must remain stopped until the flashing red lights are turned off.

27. Emergency Vehicles
Emergency vehicles respond to fires, medical emergencies, rescues, and incidents involving hazardous materials.
The driver of an emergency vehicle may disregard traffic signs, speed limits, and the direction of traffic and parking.

28. Emergency vehicles require immediate action.
When an emergency vehicle approaches from any direction, you must yield the right of way.
Avoid gawking or rubbernecking, which adds to congestion and potential conflicts.

29. Explain how to share the road with specialized vehicles such as recreational vehicles, low-speed vehicles, and snowplows.
OBJECTIVE

30. Other Specialized Vehicles
In addition to trucks and buses, you share the roadway with low-speed vehicles, snowplows, and farm equipment.

31. Snowplows and Other Equipment
At different times of the year, you may encounter very slow moving vehicles such as snowplows, farm vehicles, or construction equipment.
When passing, watch for equipment that is wider than the vehicle itself.

32. Low-Speed Vehicles
Low-speed vehicles (LSVs) include all four-wheeled vehicles (except trucks) with top speeds between 20 and 25 mph. These include golf carts and neighborhood electric vehicles (NEHs).
NEHs are growing in popularity, as they require no trips to the gas station, have no emissions, and have lower maintenance requirements.

33. LSVs come in a wide variety of designs and types.
When you encounter an LSV, be aware of its low power and lack of protection.
Be prepared to adjust your speed and position to avoid conflict.
