North Carolina’s basic speed rule combines numbers with conditions: G.S. 20-141 sets ordinary defaults of 35 mph inside municipal corporate limits and 55 mph outside, while also requiring a reasonable and prudent speed. Learn the setting attached to each number. A remembered limit cannot replace a posted restriction or justify driving too fast for rain, visibility or traffic.

Which speed and alcohol figures belong on a review card?
Keep the limit and its scope together. The table below covers ordinary Car study rules as of the verification date; posted limits and the circumstances of a drive still matter.
| Number | What to remember | Official source |
|---|---|---|
| 35 mph | Ordinary default inside municipal corporate limits, subject to applicable exceptions and posted limits | G.S. 20-141(b) |
| 55 mph | Ordinary default outside municipal corporate limits for a passenger car; posted limits can differ | G.S. 20-141 |
| 0.08 | Alcohol concentration establishing a per se impaired-driving offense; impairment is also independently prohibited | G.S. 20-138.1 |
| Under 21 | Driving with any previously consumed alcohol remaining in the body is prohibited | G.S. 20-138.3 |
The alcohol concentration is not a target for deciding whether to drive. The under-21 rule has its own scope, and the impaired-driving law also applies when an impairing substance affects the driver. Use a sober ride rather than trying to calculate a permissible drinking amount.
Does following distance have a single legal seconds answer?
G.S. 20-152 requires a reasonable and prudent following distance considering speed, traffic and highway conditions. Leave enough room to respond to what the leading vehicle does, and increase space when the conditions make stopping or seeing harder.
For example, a gap that felt comfortable on a clear, dry approach may not be appropriate after heavy rain begins. Reassess the conditions rather than treating a memorized count as permission to maintain the same gap. The speed guide connects conditions with speed selection.
Which permit milestones are easy to mix up?
The Level 1 holding period and the Level 2 driving log are separate requirements. A teen needs nine months holding Level 1 and at least 60 logged driving hours to progress, along with the other age, record and testing conditions.
| Study figure | Application | Source |
|---|---|---|
| 9 months | Required Level 1 holding period before Level 2 | Level 2 |
| 60 / 10 / 10 | Total practice hours / minimum nighttime hours / maximum counted per week | DL-4A log |
| 7 calendar days | Wait after a failed regular Class C knowledge or driving test | NCDMV tests |
Use the GDL guide for the full progression. Finishing the experience log cannot substitute for time held, and waiting out the calendar cannot substitute for the required practice.
Can a situation question be answered without a number?
Yes. Many traffic decisions depend on who must yield or what the driver must do. This question from the app’s North Carolina bank is a useful example.
When two vehicles arrive to an intersection at the same time, which one has the right-of-way when no signs or signals indicate rules?
- A. The car approaching from the right has the right-of-way.
- B. The car approaching from the left has the right-of-way.
- C. The car in which the driver sounds his horn first has the right-of-way.
- D. The car that is traveling the fastest has the right-of-way.
Show answer
A. The car approaching from the right. The simultaneous-arrival rule in G.S. 20-155 requires the driver on the left to yield. Identify the traffic control before applying it.
Key takeaways
- Attach every limit to its location, age group or licensing stage.
- Adjust speed and following distance to conditions.
- Study yielding decisions alongside numerical rules.
