When marijuana is smoked, it can begin to affect the smoker within minutes and effects can last for between two and four hours. When marijuana is eaten, it may take over an hour to begin to affect the consumer, but the effects of the marijuana may last for more than six hours.

The throttle of a motorcycle is usually located on the right handle grip. Be sure to know where all of your motorcycle's controls are located before riding.

In a group of motorcyclists, riders with less experience should be positioned toward the front of the group, just behind the leader. This will allow more experienced riders to keep an eye on them without forcing the inexperienced rider to lead the group.

The faster you drink, the more alcohol will accumulate in your body. It is never safe to operate a motor vehicle after drinking alcohol in any amount.

There are several strategies you can use to prevent someone from driving while under the influence of alcohol. You can arrange another way for them to get home, involve them in other activities to slow their pace of drinking, use any available excuse to stop them from leaving before they are sober, and get other friends involved to intervene as a group.

A passenger puts extra weight on a motorcycle, which causes the motorcycle to handle differently. Only experienced riders should carry passengers.

Distances are difficult to judge in the dark because visual cues (like shadows and light contrasts) can be missing or distorted. You should allow a longer following distance when riding at night than you do when riding during the day.

If you are being chased by a dog, downshift and approach it slowly. Then, as you approach the dog, accelerate and leave it behind. If you encounter a larger animal, brake and prepare to stop.

When being passed, it is generally safest to ride in the center portion of your lane. Riding on the side of the lane nearest the passing driver increases the danger of a collision, and riding on the side farthest from the passing driver may tempt them to return to your lane too soon.

Instead of or in addition to mechanical turn signals, operators may use hand signals to indicate turns or stops. If an operator's left arm is bent at the elbow and pointing downward, it means the operator plans to slow down or stop.

The front brake of a motorcycle is more powerful than the rear brake. The front brake supplies at least 70 percent of a motorcycle's total stopping power.

When riding behind a passenger vehicle, it is usually best to ride in the center of the lane so you will be visible in the driver's rearview mirror. Most drivers check their rearview mirrors much more often than their side mirrors, so this lane position will increase your chances of being seen.

Passengers should sit directly behind the operator and lean as the operator leans. They should sit as far forward as they can without crowding the operator, holding onto the operator's waist, hips, or belt.

Wearing goggles provides protection for your eyes, but not for the rest of your face. A face shield provides protection for your whole face and is recommended above goggles. A windshield is not an adequate substitute for a face shield or goggles.

On average, a person's body can eliminate the alcohol content of about one drink per hour. The amount of time required to lower a person's blood alcohol content (BAC) can vary, so it is safest not to operate a motor vehicle after consuming any amount of alcohol.

All motorcycles are slightly different, so you should check the controls and make sure you know the gear pattern before riding an unfamiliar motorcycle. Work the throttle, clutch, and brakes a few times prior to riding.

Most motorcycle crashes happen on short trips that are less than five miles long at speeds slower than 30 miles per hour.

When a group of motorcyclists is passing another vehicle on a two-lane road, the riders should pass the vehicle one at a time. Each motorcyclist should complete their pass before the next rider's pass begins.

To execute a swerve, press the handgrip on the side of your desired turn. Press on the opposite handgrip to return to your original direction after you are clear of the hazard.

In the state of Kentucky, a person with a minimum blood alcohol concentration (BAC) of 0.08 percent is considered legally intoxicated. It is both illegal and dangerous to operate a motor vehicle while under the influence of alcohol.

When preparing to pass another vehicle on its left, you should ride in the left portion of your lane. This will increase your line of sight and make you more visible to oncoming traffic.

When riding in a group, inexperienced riders should ride just behind the leader near the front of the group. This allows more experienced riders to keep an eye on them from the back of the group.

Usually, the best way to handle a tailgater is to get them in front of you. If you can do so safely, change lanes and let them pass. Speeding up may only increase the danger by encouraging them to follow you at a faster speed.

Like any other vehicle, motorcycles have blind spots. Always turn your head to check for traffic in your blind spot before changing lanes.

A properly chosen lane position should provide a number of benefits, including an increased ability to see others and to be seen. It should help you avoid wind blasts, other drivers' blind spots, and surface hazards. Your lane position should discourage other drivers from trying to share your lane and provide you with an escape route, should a hazard arise.
