A driver does not have to look or feel drunk for alcohol to interfere with safe driving. Blood alcohol concentration (BAC) can affect vision, judgment, coordination, and reaction time at levels below California’s legal limit.
For people traveling throughout San Bernardino, CA, those changes can have serious consequences.
What Is Blood Alcohol Concentration?
Blood alcohol concentration measures the amount of alcohol in a person’s bloodstream. As alcohol enters the blood, it affects the brain and central nervous system, including functions that people rely on behind the wheel.
It is difficult to accurately estimate BAC based on the number of drinks a person has consumed.
Factors that may affect a person’s BAC include:
- The amount of alcohol consumed
- How quickly the alcohol was consumed
- Body weight
- Whether the person has eaten
- How the individual’s body processes alcohol
Because these factors vary from person to person, feeling “fine” is not a reliable indication that someone is capable of driving safely.
How Do Different BAC Levels Affect Driving?
The effects of alcohol generally become more pronounced as BAC increases.
However, the National Highway Traffic Safety Administration (NHTSA) reports that impairment can begin at BAC levels well below 0.08%, including:
- BAC of 0.02%: Drivers may experience a decline in visual function and a reduced ability to perform two tasks at once, making it harder to recognize developing hazards.
- BAC of 0.05%: Coordination and the ability to track moving objects are reduced, leading to difficulty steering and responding appropriately to emergencies.
- BAC of 0.08%: Alcohol can impair concentration, perception, short-term memory, and speed control, significantly increasing the likelihood of a crash.
- BAC of 0.10% or Higher: Impairment becomes severe, causing substantial loss of vehicle control, difficulty maintaining lane position, and a high probability of a collision.
Driving routinely requires divided attention. Losing even some of that ability can make it harder to recognize a developing hazard and easier to get into a DUI accident.
Can a Driver Be Too Impaired to Drive Below 0.08% BAC?
Yes. The 0.08% threshold should not be confused with the point at which alcohol first affects a driver.
NHTSA has found that impairment of certain driving abilities begins below 0.08%. California’s Department of Motor Vehicles also cautions that a BAC below the applicable legal limit does not necessarily mean someone can drive safely.
California law has different BAC restrictions for certain motorists, including:
- Drivers under age 21
- Drivers on DUI probation
- Commercial drivers
- Drivers transporting passengers for hire
The safest choice after consuming alcohol is to avoid driving rather than trying to calculate whether a particular BAC is low enough to get behind the wheel.
How Can Alcohol Impairment Cause Accidents in San Bernardino?
Drivers must constantly evaluate what is happening around them and react accordingly. Alcohol can interfere with several of those abilities, making ordinary traffic situations harder to navigate safely and increasing the likelihood of a car accident.
An alcohol-impaired motorist might:
- Brake too late for slowing or stopped traffic
- Drift outside their lane
- Misjudge another vehicle’s distance or speed
- Travel too fast or too slowly for conditions
- Overlook a pedestrian, bicyclist, or motorcyclist
- Make a dangerous turn or decision at an intersection
A driver struggling with judgment, coordination, and reaction time may recognize a hazard too late or be physically unable to respond effectively once they notice it.
Why BAC Evidence Can Matter After a DUI Accident
Evidence of a driver’s alcohol consumption may help establish the circumstances surrounding a collision. However, a BAC result is only one piece of the larger picture.
An investigation into a suspected DUI accident may involve:
- Blood or breath test results
- Police reports
- Witness accounts
- Photographs and video recordings
- Statements or observations concerning the driver’s behavior
- Evidence showing how the vehicles moved before impact
Individual reactions to alcohol can also vary. Examining these materials together can provide a clearer understanding of whether impairment contributed to the collision and how the accident occurred.
