Objectives: Students will learn about using risk
reducing strategies to manage multiple-lane
roads at speeds up to 65 mph in complex risk
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 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 Entering
Alternate routes that travel around the city begin with even
 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
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
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
 Construction zones usually have slower speed
limits even on expressways
