Road signs

The divided highway ends ahead; be careful at the point where two-way traffic begins again.
Speed limit signs are regulatory: they state a rule you must obey.
Reflectors go on the end rails of narrow bridges and on other obstructions so drivers can see them clearly.
Green interstate guide signs are usually mounted overhead.
A truck symbol crossed out by a red circle and slash means trucks are not allowed.
A left arrow with ONLY (or a LEFT LANE MUST TURN LEFT sign) means traffic in that lane must turn left.
A single reflector on a post is a night-time marker that shows where the road goes.
A Stop Ahead warning sign tells you a stop sign is coming up, so be prepared to stop.

Sign shapes and colors

White and black is the color pair for regulations and instructions, the rules you must follow.
Most orange work zone signs are diamond-shaped.
The manual describes service signs as blue.
The railroad advance warning sign is a round yellow and black sign that tells you railroad tracks are ahead.

Traffic signals

A yellow X tells drivers to clear the lane.
The manual says you must obey the officer at all times when an officer is directing traffic.
With a flashing yellow left-turn arrow you must yield to oncoming traffic and pedestrians, which have the right-of-way.
A steady yellow warns that red is coming, and drivers must stop if they can stop safely before the crosswalk.
A green arrow lets you turn in its direction even though the red light remains lit.
In general a red arrow prohibits turns in its direction, and you must wait for a green signal.

Right-of-way and turning

At a yield sign you slow down and get ready to stop if vehicles or pedestrians are approaching.
Once the lead vehicle enters, the other vehicles in the procession may follow it through, whatever the signals or signs show.
The manual recommends turning at 10 mph or less.
After slowing and choosing the gear, you accelerate slightly through the turn.
A driver turning on red must yield to all pedestrians and vehicles in the intersection, bicycles included.
The manual says not to pass within 100 feet of an obstructed view or if vehicles or pedestrians might cross your path.
You look over your shoulder in the direction you will be moving.

Alcohol and drugs

For a BAC over 0.05 but under 0.08, conviction brings a fine of $100 to $500, up to 6 months in jail, or both.
A second Zero Tolerance revocation lasts 12 months.
Drugs other than alcohol can impair thinking and driving even more than alcohol does.
Even a small amount of alcohol or drugs weakens your judgment, your decisions and how fast you act.
Driving or being in actual physical control means you have agreed to take one or more blood alcohol content (BAC) tests.
A third or later offense carries a fine of not more than $5,000.

Speed and following distance

The manual notes that wide tires can hydroplane even at reduced speeds.
Fog, rain or darkness can make even the posted limit too fast, so you must slow down for the conditions.
The manual says to slow down and prepare to stop, so you avoid being hit from behind.
The estimated braking distance is 83 to 167 feet at 50 mph.
If you drive too fast for your lights, you cannot stop within the distance they let you see.
Maximum braking is just before the wheels lock; too much pressure locks them and the vehicle skids.
Being within the posted limit does not excuse failing to stop; it means your speed was unsafe for conditions or you followed too closely.

Licensing basics

A driver with restriction T may drive from 5 a.m. to 10 p.m. unless one of the listed exceptions applies.

A left turn is shown by an arm and hand extended straight out of the window.
You back slowly into the lane that is closest to you for the direction you will go.

Pavement markings

Two-lane highways have a single broken yellow centerline.
Pavement markings show places where visibility is limited and passing is dangerous.
Hills and curves are no-passing places whether or not the road has markings.
You keep to the right of the centerline and cross it only to pass when you can do so safely.

Expressway driving

The manual says to maintain a constant speed and not speed up or slow down without good reason.
You keep your speed with the traffic until you reach the exit, and slow down later in the deceleration lane or on the ramp.

Parking rules

A car on an incline can roll if the parking brake is not set or is not working, or if it is not braced against the curb.
Signs prohibiting stopping make parking in that place illegal.
Spaces reserved for disabled people are only for vehicles with a disabled license plate or a disability placard.
Downhill, you shift into reverse or park after the wheel touches the curb.

Railroad crossings

Another train may be on a different track, so check both directions before going.
Stay stopped until the gates are fully raised and the lights have stopped flashing.
Advance warning signs tell you a highway-rail crossing is ahead.

Pedestrians

The manual suggests a stop hand signal or several taps on the brakes to flash your brake lights.
You stop outside the crosswalk so you do not block the path of the blind person.
A flashing hand means pedestrians already in the intersection continue, while others stay at the curb.

Sharing the road

Riders need the full width of the lane to respond to hazards, and a motorcycle has the right to use the lane.
A cyclist can turn right on red after slowing down and yielding to traffic.
Animal-drawn vehicles have the same rights to use the road as a motor vehicle.
Roads with animal crossing signs call for extra alertness.

Child restraint systems must meet the federal crash-test standards set by the U.S. Department of Transportation.

Distractions and phone use

Cognitive distraction is thinking about anything other than driving.
The manual says Oklahoma law requires drivers to give their full attention to the road.
Loose items that can fall to the floor may distract you, so the front seat should be clear of them.

Emergencies and crashes

The penalty may include up to 30 days in jail, along with or instead of a fine.
