1 Driving on Expressways
Chapter 11

2 Characteristics of Expressway Driving
Name five reasons expressways have lower collision rates than other highways. Cross traffic is eliminated Expressways have a median or barrier between opposing lanes of traffic

3 Lower Collision Rates Pedestrians, non-motorized vehicles, and slow-moving vehicles are not permitted on most expressways. Wide shoulders and extra-wide underpasses provide good escape paths. Expressway signs are designed to help drivers anticipate conditions well ahead.

4 Expressway Interchanges
Trumpet Interchange

5 Expressway Interchanges
Cloverleaf Interchange

6 Expressway Interchanges
Diamond Interchanges

7 Expressway Interchanges
All-Directional Interchange

8 Strategies for Driving on Expressways
Travel at about the same speed as other vehicles Conform to posted minimum and maximum speed limits Have your headlights on at all times so that you are more visible to other drivers

9 Expressway Strategies for Short Distances
Have a travel plan Know the name, route or number for both entrance and exit ramps you will use

10 Express Strategies for Long Distances
Plan stops for food, fuel, and rest Make every effort to stay alert, use the IPDE Process constantly and be aware of traffic conditions in all your zones at all.

11 How to Enter An Expressway Properly
The entrance ramp gives you time to evaluate zone conditions and determine the best speed as you prepare to enter the expressway.

12 Expressway Entrances The acceleration lane is usually long enough for you to search for a gap in which to merge and accelerate to the speed of traffic on the expressway.

13 Expressway Intersections
The merging area is the third part of an expressway entrance where vehicles blend into the expressway traffic. Evaluate how much time and space you have in your open front zones for merging into the flow of traffic. Try to merge at the same speed as the vehicles in the nearest lane.

14 Entrance Ramp Problems
Entering the wrong entrance ramp Other vehicles Restrictions on line of sight to expressway Signs Acceleration Lane Problems

15 Entering From the Left What some problems of entering the expressway form the left? Faster traffic Blocked view due to head restraints, roof, walls Harder to see smaller cars, motorcycles

16 When Should the 3-Second Rule Be Increased?
Following a large vehicle that is blocking your vision Following a motorcyclist Driving in bad weather or roadway conditions Driving in heavy traffic Being Tailgated Driving a heavy vehicle or pulling a trailer Operating a motorcycle Entering or Exiting an expressway

17 Lane Changing Change lanes one at a time
Check traffic in outside and rearview mirrors as well as blind spot If your path is clear, accelerate gently and move to the next lane Cancel your signal once you have changed lanes

18 Exiting the Expressway
Look of the Green guide sign and about half a mile from the exit, signal and be in the lane closest to the exit

19 Exiting the Expressway
Try not to decelerate until you are in the deceleration lane Move to the deceleration lane and cancel your signal Slow gradually and keep a safe space cushion ahead and behind you Identify the ramp speed limit and whether or not you will need to yield or stop

20 Highway Hypnosis What is Highway Hypnosis?
When you have been driving for a long period of time you may be lulled into an inattentive, drowsy state More than 100,000 collisions in the US each year are caused by sleepiness

21 Velocitation What is Velocitation?
Velocitation occurs when hours of driving fools you into thinking your vehicle is traveling slower than it really is. You might then unconsciously drive too fast.

22 Disabled Vehicle Check rear zones and signal. Pull as far as possible onto the shoulder or the median. Turn on your hazard lights. If the vehicle is not very far off the road, get everyone out and away from the vehicle.

23 Disabled Vehicle 3) When it is safe to do so, raise the hood and tie a white cloth to the antenna or door handle. If you have a cell phone, call for help. 4) If you have emergency flares or reflectors, set them out at least 500 feet behind your vehicle when it is safe to do so.

24 Disabled Vehicle 5) Get back into your vehicle and lock all doors. Ask anyone who stops to assist you to go to a phone and call for help. Never get into a stranger’s vehicle. 6) Do not stand in the expressway to direct traffic

25 Tollbooths Tollbooths are apart of driving in Illinois. When driving on a “Toll Road” you should: Carry money if you do not have an I-pass Slow down to the designated speed limit Beware of your surroundings

26 Using Expressways Safely
The three key factors that contribute to safe driving on expressways are: Cooperation among drivers Concentration on the driving task Use of the IPDE Process
