There are several major factors that can affect a person's blood alcohol concentration (BAC). A BAC is determined in part by the amount of alcohol someone has consumed, how fast they consumed the alcohol, and their body weight.

Before every ride, be sure to check your tires' inflation pressure, your tires' treadwear, and the general condition of the sidewalls and tread surface on the tires.

Choosing a brightly-colored helmet is recommended. Not only will the helmet protect you in the case of a crash, but the bright color of the helmet will help other road users see you.

A properly chosen lane position should protect your lane from other drivers while communicating your intentions to them.

The center of a lane can be especially hazardous when wet. When it begins to rain, avoid the center of the road by riding in the tire tracks left by cars. The left tire track is often the best option.

The engine cut-off switch is generally located next to the right handgrip. It is important to know where all of your motorcycle's controls are located before starting out.

Do not try to accelerate out of a wobble because doing so will only make the motorcycle more unstable. Instead, grip the handlebars firmly, slow down by gradually closing the throttle, move your weight as far forward and downward as possible, and pull off the road as soon as you can. Avoid applying the brakes, as this may also worsen the wobble.

While a staggered group formation is usually best, it is better to switch to a single-file formation when turning, taking curves, or entering or exiting a highway.

Shifting your motorcycle into a lower gear causes an effect similar to applying the brakes. This is known as engine braking.

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

Because motorcycles are small in stature and have fewer and smaller lights than other vehicles, they can be difficult to see. For your safety, it is best to ride defensively and assume that others on the road do not see you.

If either of your tires go flat while you are riding, hold the handgrips firmly, ease off the throttle, and maintain a straight course. If you need to brake, gradually apply the brake to the tire that is not flat. As you slow down, edge to the side of the road, squeeze the clutch, and stop.

It is dangerous to ride directly alongside a vehicle in another lane because you may be in the vehicle's blind spot and the driver will have no way of knowing you are there. It can also be dangerous because the vehicle may block your path of escape if another hazard arises.

When hazards exist to your left, it is often best to ride in the right portion of the lane. Be prepared to adjust your lane position as road and traffic conditions change.

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 behind them to keep an eye on them.

A staggered formation is generally best when riding in a group. You should move into a single-file line when turning, riding in a curve, or entering or exiting a highway.

To maintain directional control through a turn, you should look through the turn by turning only your head. Slow down before turning and lean your motorcycle in the appropriate direction.

Make sure that you are aware of the locations of all your motorcycle's controls before beginning to ride. The horn button on a motorcycle is usually located next to the left handgrip.

Nothing guarantees that a driver sees you. It is safest to assume that if another vehicle can enter your path, it will.

When taking a long trip, be sure to schedule in frequent breaks to rest and try not to ride more than six hours in one day. Wind, cold, and rain can make you tire quickly, so be sure to dress to protect yourself from the elements. Avoid taking artificial stimulants, as the effects when they wear off can be very dangerous.

Gloves can provide you with an improved grip on your motorcycle's handlebars. They can also protect your hands in the event of a crash.

It is recommended that you thoroughly check your motorcycle before every ride. Doing this can help you identify mechanical defects or equipment failures that could endanger you.

The front brake of a motorcycle is more powerful than the rear brake. It supplies at least three-quarters of the motorcycle's total stopping power.

You must use proper turn signals every time you turn or change lanes, even if you think your intentions are obvious. Signals are always important, even if no one else seems to be around to see them. There may be other vehicles nearby that you can't see or haven't yet noticed.

Riding safely at night is challenging because it is harder to see and be seen than it is during the day. The absence of normal shadows and light contrasts makes it harder to judge distances.

In potential high-risk areas, such as school zones or construction zones, cover the clutch and both brakes. This cuts down the amount of time you will need to react to a hazard.

Maintaining a cushion of space on all sides of your motorcycle helps to ensure that you have time and space to react if another road user makes a mistake.

Gloves should be made of leather or another durable material to provide proper protection for the wearer.

Loads should be positioned forward with heavier items toward the front of the load. Loads should be over or in front of the rear axle. Lighter items should be packed behind you.

Inexperienced riders should ride near the front of a group, just behind the leader, so more experienced riders can keep an eye on them from behind.
