What is the primary safety benefit of wearing a seat belt?
Reduces the risk of being ejected from the vehicle in a crash
Improves fuel efficiency
Decreases road noise
Prevents tire blowouts
Wearing a seat belt secures occupants and significantly reduces the chance of being thrown out of the vehicle during a collision. This containment is the main way seat belts save lives. Other options are unrelated to seat belt function.
What is the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over in most US states?
0.08%
0.05%
0.10%
0.15%
Most US states have set the legal BAC limit at 0.08% for drivers aged 21 and over. Driving at or above this level is considered impaired and can lead to DUI charges. Lower limits apply in some jurisdictions, but 0.08% is the standard.
Which of the following is a direct factor that increases the risk of drunk driving?
Consuming alcohol before getting behind the wheel
Driving during daylight hours
Wearing sunglasses while driving
Using cruise control on highways
Consuming alcohol impairs judgment, coordination, and reaction time, directly increasing the risk of driving accidents. Daylight driving, sunglasses, and cruise control do not inherently increase drunk driving risk. Alcohol consumption is the key risk factor.
A three-point seat belt secures which parts of the body?
Shoulder and lap (chest and pelvis)
Head and shoulders
Arms and waist
Legs and chest
A three-point seat belt has a strap across the chest and another across the pelvis, securing the upper body and hips. This configuration distributes crash forces over stronger body parts. The other options describe incorrect strap placements.
What is one effective personal strategy to prevent a drunk driving incident?
Plan for a designated driver or call a taxi
Drive at a slower speed than usual
Eat a large meal before drinking
Switch lanes frequently
Designating a sober driver or arranging a taxi ensures you don't drive after consuming alcohol. Slowing down, eating food, or changing lanes do not prevent impairment from alcohol. The designated driver strategy directly removes the risk.
Which of the following does NOT affect an individual's blood alcohol concentration (BAC)?
Wearing a seat belt
Body weight
Food consumption before drinking
Gender
BAC is influenced by body weight, gender, and how much food is in the stomach, but seat belt usage does not alter metabolism or absorption of alcohol. Seat belt wearing is unrelated to BAC levels. The other factors directly impact BAC.
By approximately how much can reaction time be delayed at a BAC of 0.08%?
20 - 50% slower
5% slower
Unchanged
10% slower
At 0.08% BAC, reaction times can be delayed by 20 - 50%, significantly increasing stopping distances. Lower BAC levels have smaller effects, while zero change is incorrect. The 20 - 50% range reflects typical impairment research.
What is the primary reason for checking your seat belt before starting to drive?
To ensure the belt fits properly and locks in a crash
To adjust the rearview mirror
To test the brake lights
To set the cruise control
Verifying that the belt fits snugly across the pelvis and shoulder and will lock during sudden deceleration is essential for occupant protection. Mirror adjustment, brake lights, and cruise control do not relate to seat belt safety. Proper fit is critical.
Which community-level strategy has been shown to significantly reduce drunk driving incidents?
Mandatory ignition interlock devices for DWI offenders
Lowering speed limits
Adding extra highway lanes
Installing speed bumps in residential areas
Ignition interlock devices prevent vehicles from starting when the driver's BAC exceeds a threshold, effectively reducing repeat DUI incidents. Speed limits and infrastructure changes have different safety impacts, but they do not directly prevent drunk driving.
An unbelted occupant is approximately how many times more likely to be ejected in a crash compared to a belted occupant?
30 times more likely
5 times more likely
10 times more likely
25 times more likely
Studies show that not wearing a seat belt makes a person about 30 times more likely to be ejected in a crash. Ejection greatly increases the risk of severe injury or death. The other figures underestimate the ejection risk increase.
Which of the following is often the first cognitive impairment after consuming alcohol?
Reduced inhibition and judgment
Night vision loss
Total loss of hearing
Complete paralysis
Alcohol first impairs judgment and reduces inhibitions, leading to riskier behaviors. Vision and motor impairments occur as BAC rises further. Total hearing loss and paralysis are not effects of moderate alcohol consumption.
Where should the lap portion of a seat belt be positioned?
Across the pelvis, not the abdomen
Across the stomach
Behind the back
Across the thighs
The lap belt must lie across the strong pelvic bones to distribute crash forces safely. Placing it over the abdomen risks internal injuries. The other placements offer poor protection or discomfort.
On average, how long does it take the liver to metabolize one standard drink?
About one hour
About 15 minutes
About 30 minutes
About 2 - 3 hours
The liver typically processes one standard drink (about 14 grams of alcohol) in roughly one hour. Metabolism rates vary slightly, but 15 - 30 minutes or several hours are inaccurate averages. One hour per drink is the standard guideline.
What defines a primary seat belt law in many jurisdictions?
Officers can stop and cite solely for a seat belt violation
Seat belt use is only recommended, not required
Fines are only issued if another violation occurs
Only front-seat passengers must buckle up
A primary law allows officers to pull over a vehicle for just a seat belt violation, enhancing enforcement and compliance. Secondary laws require another traffic violation first. Recommendation or partial requirements do not define primary laws.
By approximately what percentage do seat belts reduce the risk of fatal injury for front-seat occupants in cars?
45%
25%
60%
80%
Seat belts reduce the risk of fatal injury in car crashes by about 45% for front-seat occupants. They distribute crash forces and prevent ejection. The other percentages overstate or understate the standard reduction.
How does alcohol consumption specifically impair a driver's vehicle control?
By narrowing peripheral vision and reducing smooth tracking of moving objects
By strengthening central vision exclusively
By increasing manual dexterity
By improving reaction speed
Alcohol narrows peripheral vision (tunnel vision) and degrades smooth pursuit eye movements needed to track moving targets. These visual impairments, combined with delayed processing, worsen vehicle control. It does not enhance vision or reaction speed.
A 160-pound male consumes three standard drinks over two hours. Roughly what BAC would he reach?
Approximately 0.03%
Approximately 0.06%
Approximately 0.08%
Approximately 0.10%
On average, one standard drink raises BAC by about 0.02% in a 160-pound male. Three drinks give roughly 0.06%, but two hours of metabolism at 0.015% per hour lowers it by 0.03%, resulting in about 0.03%.
Which policy intervention has the strongest evidence for reducing DUI recidivism?
Mandating ignition interlock devices for all DWI offenders
Lowering general speed limits
Extending open container laws to rest areas
Increasing highway lighting
Ignition interlock systems directly prevent a vehicle from starting if the driver's BAC is too high, which significantly reduces repeat offenses. Traffic engineering and open container laws have safety benefits but less impact on recidivism.
In a high-speed rollover crash, properly wearing a seat belt reduces the fatal injury risk by approximately what percentage?
75%
30%
50%
90%
In rollovers, seat belts reduce fatal injury risk by about 75% because they keep occupants inside the vehicle and distribute forces. Lower percentages understate this high-protection scenario, while 90% overstates typical results.
Which community strategy focuses on primary prevention of drunk driving?
Designated driver programs
Installing ignition interlocks
Random sobriety checkpoints
Automatic speed camera enforcement
Designated driver programs aim to prevent impaired individuals from driving before it occurs, fitting primary prevention. Interlocks and checkpoints are secondary measures that detect or restrict after an offense. Speed cameras target speeding, not alcohol impairment.

Cheat Sheet

  1. Why Drunk Driving and Skipping Seat Belts Are a Dangerous Duo - Did you know that booze-fueled impaired drivers are the least likely to click that little click on a seat belt? Skipping this simple belt doubles the risk of fatal injuries when things go sideways on the road. ajph.aphapublications.org
  2. BAC Limits: How Low Should You Go? - Most countries set the legal blood alcohol concentration at 0.08%, but some have lowered it to 0.05% to keep drunk driving rates down. Studies show that tighter limits can cut fatal crashes, especially when law enforcement and public awareness are on point. en.wikipedia.org
  3. Seat Belt 101: Buckle Up Like a Pro - A snug belt across your lap and shoulder is your best friend in a crash, stopping you from flying forward like a superhero gone wrong. Always buckle up before you crank that engine - you'll thank yourself later! nhtsa.gov
  4. Liquid Courage vs. Reaction Time: The Showdown - Alcohol slows your brain, making you react to hazards at the pace of a snail racing a cheetah. When milliseconds count, that fuzzy feeling can lead to fender benders or worse. nhtsa.gov
  5. Smart Strategies to Stop Drunk Driving in Its Tracks - Sobriety checkpoints, a minimum drinking age of 21, and eye-catching community campaigns have proven to put the brakes on impaired driving. Get creative - share rides, plan alcohol-free hangouts, or even host mocktail nights with friends! cdc.gov
  6. Primary Enforcement: When Cops Can Stop You for Buckling Up - In states with primary seat belt laws, officers don't need another excuse to pull you over - skipping your belt is enough. This power leads to higher seat belt use and fewer traffic fatalities. pubmed.ncbi.nlm.nih.gov
  7. Alcohol vs. Seat Belts: A Risky Relationship - As BAC levels climb, confidence may soar - but seat belt use plummets in tandem, piling risk upon risk. Buckling up is the perfect countermeasure to alcohol's reckless sidekick. ajph.aphapublications.org
  8. The Power Combo: Stricter BAC and Seat Belt Laws - When lower BAC thresholds meet primary seat belt enforcement, traffic fatalities take a nosedive faster than you can say "safety first." Layering laws gives drivers - and everyone else - a better shot at getting home safe. researchgate.net
  9. Spread the Word: Public Education Campaigns - Eye-catching ads, school programs, and community challenges make sober driving and seat belt use the next big trend. When everyone's talking about safety, more people buckle up and ride sober. cdc.gov
  10. Legal and Personal Consequences: Don't Bet Your Life - Beyond fines and license suspensions, drunk driving can lead to jail time, lifelong guilt, or tragic loss. Remember, no party is worth a lifetime of regret - choose a designated driver or grab a cab instead. nhtsa.gov
