MODULE 6 Objectives: Students will learn about using risk reducing strategies to manage multiple-lane roads at speeds up to 65 mph in complex risk environments Topics Covered: — Characteristics of Expressway — Entering, exiting traffic, steering, establishing speed and lane positions, and traveling on multiple-lane roadways — Managing interchanges, merging, exiting from traffic flow, and selecting vehicle positions in expressway driving Expressways Expressways include interstate highways, freeways, turnpikes, toll roads, parkways, and beltways—high speed roadways—divided by a barrier/medium— limited access highways — Have no traffic lights and many signs are designed to break away when hit by a vehicle — Have exits and entrances only at certain locations — Have two or more lanes going in one direction — Have no cross traffic — Have higher injury severity rates — Rumble strips are installed on the edge of roads to alert drivers who drift off the road — Are designed so that traffic either entering or exiting has separate lanes from fast moving traffic and for low-risk high speed driving Expressways Types/Signs Diamond expressway (interchanges) allows a driver to reenter the expressway by moving across the intersection of the secondary road A trumpet interchange allows for interchange of second twoway streets to a multiple lane roadway with minimal traffic mix Cloverleaf interchange allows two expressways to cross with minimal disruption — When entering an expressway, motorist should try to enter at the same speed as traffic already on the expressway — The maximum speed limit on rural expressways in North Carolina is 65 mph Interstate signs shaped like a shield are red, white and blue Expressways Signs HOV (high occupancy vehicle) lanes are marked with a diamond The red X over a lane means that traveling in that lane is prohibited An interstate route with even numbers travel east and west routes An interstate route with odd numbers travel north and south routes The far right lane should be used for slower traffic; the far left lane should be used for faster traffic Never go in reverse when you are driving on an expressway Expressway Entering Alternate routes that travel around the city begin with even numbers A solid yellow line on any roadway should be on the drivers left side The correct procedures for entering an expressway is to read ramp signs, search ahead and behind for gaps in traffic, adjust speed, merge and blend with traffic Motorist should try to enter an expressway at the same speed as traffic already on the expressway — If a driver mistakenly enters the wrong entrance ramp and is headed in the wrong destination -- continue on in that direction until you come to the next exit — The most dangerous mistake to make when entering an expressway is entering the exit ramp Expressway Speeds At expressway speeds, you should maintain a following distance of at least 3-4 seconds — Peripheral vision is affected by the speed of the vehicle The correct procedures for changing lanes is check traffic ahead, behind, beside, signal, select gap, check blind spots, adjust speed, steer smoothly into lane, and cancel signal A driver should increase their following distance on an expressway when — — — Weather conditions are bad Following large trucks Being tailgated Driving with the flow of traffic is the best way to maintain a space cushion around your vehicle Expressway Passing and Exiting Passing on an expressway includes special challenges for the novice driver which are — Higher speeds — Passing on the right and left — Vehicles and drivers on both sides moving into the same lanes When exiting an expressway, it is important to — Plan your exit in advance — Signal any changes in position — Move to the lane nearest the deceleration—this lane allows the driver exiting the time and space needed to adjust vehicle speed The best way to be prepared for a blocked lane is to allow for an escape route to one side of your vehicle Managing Interchanges When driving in large cities, traffic may stop abruptly—drivers must be attentive and prepared A driver should increase their following distance when sleepy, being tailgated, and following an SUV —A dulled, drowsy, trance-like condition while driving is known as highway hypnosis If you miss an exit, you should continue on to the next exit and turn around—never make a U-turn on expressways Construction zones usually have slower speed limits even on expressways What are the three most common expressway interchange types?The three most common expressways interchange types are cloverleaf, diamond and trumpet interchanges.
What is the maximum speed limit on rural expressways in Colorado?
Do limited access highways have exits and entrances only at certain locations?They are called limited or controlled access highways because there are only certain locations, called interchanges, where a driver can enter and exit the expressway. Expressways have a low frequency of collisions, but often have high injury severity rates when a crash does occur because of the higher speeds.
What are the characteristics of an expressway?List the 5 characteristics of an expressway. Controlled access, High-speed traffic, Divided by a barrier, Vehicle restrictions, and Multiple lanes.
