Driving Points & ETG Testing — FAQ
Answers to the questions people search most before using our free calculators.
How do I check how many points are on my driving license?
Select your country or state in the Driving License Points Calculator, tick each violation on your record, and see your total demerit points against your region's limit — USA (DMV), UK (DVLA), Canada, and Australia supported.
How many demerit points before license suspension?
It depends on your region and license type. California often uses 4 points in 12 months; the UK allows 12 points in 3 years. Use the License Suspension Risk Calculator for a percentage estimate based on your violations.
What is an ETG test and how long does alcohol show in urine?
CalcGrain models urinary ETG with a biphasic decay curve (3.5-hour fast phase, 9-hour slow tail). Light-to-moderate drinking often clears a 300 ng/mL cutoff in roughly 24–45 hours; sensitive 100 ng/mL panels may remain positive for roughly 45–72 hours. Cutoffs of 100, 300, and 500 ng/mL are common. Try the ETG Detection Time Calculator or EtG Alcohol Calculator for estimates.
What is an ETG calculator or ETG test calculator?
An ETG calculator (EtG alcohol calculator) estimates ethyl glucuronide in urine from standard drinks, body weight, and hours since your last drink, then compares the estimate with 100, 300, and 500 ng/mL lab cutoffs. For hours-until-clear, use the ETG Detection Time Calculator. Estimates are educational — not a laboratory result.
Do traffic tickets increase insurance rates?
Moving violations often raise premiums. The Car Insurance Points Rate Estimator projects annual surcharge based on violation type and region — a directional estimate, not a quote.
When do license points expire or fall off?
Expiry periods vary — often 12 months to 3+ years depending on jurisdiction. The Demerit Points Expiration Calculator shows when points may drop off your record.
Are these calculators legal advice?
No. CalcGrain provides simplified informational estimates only. Always confirm with your official licensing authority (DMV, DVLA, provincial ministry, etc.) or a licensed attorney.
Sourced & Cited
Every estimate is grounded in published NIAAA, SAMHSA, and official DMV/DVLA guidelines — never a guess dressed up as fact.
