21 Ohio BMV Temps Test Concepts You Must Know

Master the critical Ohio-specific driving laws and rules that aren't common sense.

Passing the Ohio BMV temps test requires knowing specific, non-obvious laws and numbers. Here are the 21 critical concepts you must master:

1. Ohio underage OVI limit is 0.02%

While the limit for drivers 21 and older is 0.08%, Ohio has zero tolerance for underage drinking. If you are under 21, driving with a BAC of 0.02% or higher is illegal.

2. Minimum age to get a TIPIC (permit)

You must be at least 15 years and 6 months old to apply for your Temporary Instruction Permit Identification Card (TIPIC) in Ohio.

3. The 40-question written test structure

The test consists of 20 regulations questions and 20 traffic signs questions. You need at least 15 correct answers in each part to pass (75% overall).

4. Wait period after failing

If you fail the temps test, you must wait at least 24 hours before you are allowed to retake it.

5. Curfew rules for 16-year-old drivers

Licensed drivers who are 16 years old cannot drive between midnight and 6 a.m. unless accompanied by a parent/guardian, or for work/school.

6. Curfew rules for 17-year-old drivers

For 17-year-old drivers, the curfew is slightly later, from 1 a.m. to 5 a.m., with the same exceptions.

7. Passenger limit for new teen drivers

During the first 12 months of holding a probationary license, drivers under 18 may only carry one passenger who is not a family member, unless a parent/guardian is in the front seat.

8. Total supervised driving hours

Teens under 18 must log at least 50 hours of practice driving, which must include at least 10 hours of night driving, certified by a parent or guardian.

9. Driver education requirements

Teens under 18 must complete an approved driver education course consisting of 24 hours of classroom instruction and 8 hours of behind-the-wheel instruction.

10. School zone speed limit

The speed limit in school zones in Ohio is 20 mph during recess and when children are arriving or leaving school.

11. Alley speed limit

The speed limit in municipal alleys is 15 mph unless otherwise posted.

12. Default residential speed limit

The default speed limit in municipal residential and business districts is 25 mph.

13. State route speed limits

The speed limit on state routes outside urban districts is 50 mph. Inside municipal corporations outside business districts, it is 35 mph.

14. Rural freeway speed limit

The maximum speed limit on rural freeways and the Ohio Turnpike is 70 mph.

15. Distracted driving is a primary offense

Ohio law prohibits holding or supporting a cell phone while driving. For drivers under 18, utilizing any electronic device (even hands-free) is illegal and acts as a primary offense.

16. The Move Over Law

You must change lanes or slow down when passing stationary emergency vehicles, tow trucks, and construction or maintenance vehicles with flashing lights.

17. Implied Consent chemical test refusal

Refusing to take a chemical test under Ohio's Implied Consent Law leads to an automatic 1-year administrative license suspension.

18. The 12-point suspension rule

Accumulating 12 or more points on your Ohio driving record within a 2-year period triggers an automatic 6-month license suspension.

19. Minimum tire tread depth

Tires must have a minimum tread depth of at least 1/16 of an inch to be considered safe and legal in Ohio.

20. Headlight activation rules

Headlights must be turned on from sunset to sunrise, in fog, or whenever your windshield wipers are in continuous use.

21. Seatbelt requirements

Ohio requires seatbelts for all front-seat occupants. However, if the driver is under 18, every passenger in the vehicle must wear a seatbelt.
