Will I get a fine for doing 36 in a 30?

Possibly. The typical NPCC prosecution threshold in a 30 mph zone is 35 mph (10% plus 2 mph). At 36 mph you are technically above that threshold, so prosecution is possible. In practice, most forces would offer a speed awareness course for speeds in the 35–42 mph range, including 36 mph. You would not typically receive a fixed penalty notice at 36 mph — the more likely outcome, if anything is issued, is a course offer. However this is discretionary and not guaranteed.

Will I get points for doing 35 in a 30?

At 35 mph in a 30 zone you are at the typical NPCC prosecution threshold — the point at which most forces consider taking action. If enforcement proceeds, you would typically be offered a speed awareness course rather than a fixed penalty notice (no points). A fixed penalty with 3 points is more likely above 42 mph. That said, the threshold is discretionary — not a legal right — and varies by force.

What happens if you're caught doing 40 in a 30?

At 40 mph in a 30 zone you are within the typical speed awareness course window (35–42 mph). You would likely be offered a course — no points, fee of around £80–£100. If you have already attended a course in the last 3 years you are not eligible and would receive a fixed penalty notice: £100 and 3 penalty points.

What happens if you're caught doing 45 in a 30?

At 45 mph in a 30 zone you are in Band B territory — significantly above the course eligibility threshold. The likely outcome is a fixed penalty notice (£100 and 4–6 points) or a court summons. At court, Band B carries a fine of 75–125% of your weekly net income and 4–6 points or a 7–28 day driving ban.

What happens if you're caught doing 50 in a 30?

At 50 mph in a 30 zone you are in Band C — 20 mph above the limit. This is a court matter. The Sentencing Council guidelines for Band C set a starting fine of 150% of weekly net income (range 125–175%) and either 6 penalty points or a driving disqualification of 7–56 days. Magistrates take into account aggravating factors, including the road type and whether other road users were present.

Is 34 mph in a 30 zone an offence?

Yes — legally, any speed above the limit is an offence. At 34 mph you are below the typical NPCC prosecution threshold of 35 mph, so in practice most forces would not take action. However this is a discretionary guideline, not a legal right. Police Scotland applies zero tolerance and would prosecute at any speed above 30 mph.

36 in a 30: Will I Get a Fine? What Happens at Every Speed Over 30 mph

Quick answer

At 36 mph in a 30 zone, most UK forces would offer a speed awareness course — no points, fee of around £80–£100. The typical prosecution threshold is 35 mph, and courses are usually offered up to around 42 mph. Above that: fixed penalty (£100 + 3 points). Above around 51 mph: court, with possible disqualification.

Getting caught by a speed camera in a 30 mph zone is stressful — and the first question most drivers ask is what, exactly, is about to happen to them. The answer depends almost entirely on the recorded speed. This article gives a clear outcome for every speed from 31 mph upwards, explains the thresholds and why they exist, and covers what you can expect from the process.

The three zones in a 30 mph limit

Before looking at specific speeds, it helps to understand the three outcome zones. They are not defined by law but by a combination of the NPCC enforcement guideline and the National Driver Offender Retraining Scheme (NDORS) criteria for course eligibility:

Below prosecution threshold (~31–34 mph) — technically an offence, but most forces would not take action under the NPCC guideline of 10%+2 (35 mph in a 30 zone)
Course window (~35–42 mph) — eligible for a speed awareness course: no points, no fine through the courts, educational half-day programme instead
Fixed penalty / court (43 mph+) — fixed penalty notice (£100 and 3 points) for Band A, court summons with income-based fine and possible disqualification for Band B and C

⚠️ These are typical outcomes, not guaranteed ones. The NPCC threshold is a discretionary guideline — not a law. Police Scotland applies zero tolerance. Some forces set tighter thresholds in school zones, roadworks, or accident black spots. The recorded speed in your specific case determines your outcome.

Speed-by-speed guide for a 30 mph zone

The table below shows the typical outcome for each speed in a 30 mph zone, based on NPCC guidelines and Sentencing Council bands. Use it as a guide — not a guarantee.

Speed	Typical outcome	Detail
31–34 mph	Unlikely to prosecute	Below the typical NPCC prosecution threshold of 35 mph. An offence in law, but most forces would not take action. Exception: Police Scotland (zero tolerance).
35–42 mph	Speed awareness course offered	No points. Course fee ~£80–£100. Not available if you attended a course in the last 3 years — in that case, fixed penalty instead.
43–50 mph	Fixed penalty / Band B court	£100 + 3 points (FPN) or court: 75–125% weekly income, 4–6 points or 7–28 day ban.
51 mph+	Band C — court	125–175% weekly income, 6 points or 7–56 day disqualification. Magistrates may impose longer bans for extreme speeds.

What happens at each specific speed

34 mph Unlikely to prosecute

Below the typical NPCC prosecution threshold of 35 mph. In practice, most forces would not take action. Technically an offence in law — Police Scotland and forces applying tighter thresholds in specific locations could still prosecute. No reasonable expectation of receiving a NIP at this speed in most of England and Wales.

35 mph Course or no action

The typical NPCC prosecution threshold. At exactly 35 mph, some forces may not act; others would offer a course. You are at the margin — the recorded speed (which accounts for camera calibration) matters here. If a NIP arrives, a course offer is the most likely outcome.

36–38 mph Speed awareness course

Clearly within the course window. If a NIP arrives, expect a speed awareness course offer — no points, fee of around £80–£100. The only reason you would not receive a course offer is if you attended one in the previous 3 years (in which case: fixed penalty, £100 + 3 points).

39–42 mph Speed awareness course

Still within the typical course window, though approaching the upper limit. Course offer likely if eligible. At 42 mph you are right at the boundary — some forces may offer a course, others may issue a fixed penalty. Above 42 mph the course is generally not available.

43–50 mph Fixed penalty or court (Band B)

Above the course window. Outcome is either a fixed penalty notice (£100 + 3 points for Band A at the lower end) or a court summons for Band B speeds. Band B in a 30 zone runs from around 43–50 mph: fine of 75–125% of weekly net income, 4–6 points or a 7–28 day driving ban. Your specific recorded speed, driving record, and any mitigating factors affect where in the range magistrates land.

51 mph+ Court — Band C

At 51 mph in a 30 zone you are 21 mph above the limit — Band C. This is a court matter. Starting fine is 150% of weekly net income (range 125–175%), plus either 6 penalty points or a disqualification of 7–56 days. Magistrates will consider aggravating factors: time of day, road type, other road users present. Speeds above 60 mph in a 30 zone risk a longer ban.

Why 35 mph is the threshold in a 30 zone

The number comes from the NPCC enforcement guideline: 10% of 30 is 3, plus 2 gives 35. This formula is not arbitrary — it accounts for two technical factors.

First, speed detection equipment has a certified measurement tolerance of ±2 mph below 66 mph. Prosecuting a driver at exactly 31 mph risks a conviction collapsing in court if the device's tolerance is factored in. The +2 mph provides a buffer that ensures the evidence is reliable.

Second, vehicle speedometers are permitted under law to over-read by up to 10% — they must never under-read. A driver whose speedometer shows 30 mph may genuinely be travelling at up to 30 mph, or as slowly as 27 mph. The 10% element gives the driver reasonable credit for relying on their dashboard. Together these two factors produce the 35 mph starting point.

What this means in practice: the threshold exists for technical and evidential reasons. It is not permission to drive at 34 mph, and no driver has a legal right to it.

The 3-year rule and why it matters at these speeds

If you are eligible for a speed awareness course — speeds of roughly 35–42 mph in a 30 zone — there is one condition that overrides everything else: whether you attended a course in the previous 3 years. The 3-year window is measured from the date of the previous offence, not from the date you attended the course.

If you are within that window, the course offer disappears. The outcome becomes a fixed penalty notice: £100 and 3 points. There is no discretion and no appeal.

This catches many drivers out. If you attended a course in July 2023 for an offence in May 2023, and you are caught again in April 2026, you cannot attend a course — the 3 years from May 2023 does not expire until May 2026. The calendar date of the offence is what counts.

New drivers — the stakes are higher

If you passed your driving test within the last 2 years, the calculation changes significantly. Under the new driver provisions, just 6 penalty points from any combination of offences causes automatic licence revocation — you revert to learner status and must retake both the theory and practical tests.

A single fixed penalty for a 36 mph offence (if you are not eligible for a course) gives you 3 points. If you already have 3 points from a previous offence, you are at 6 — revocation. For new drivers, taking the course wherever possible is not just preferable — it may be the difference between keeping your licence and losing it.

What about 36 in a 30 — the specific question

To answer the most common search directly: at 36 mph in a 30 mph zone, the most likely outcome — if the offence is pursued — is a speed awareness course offer. You are 1 mph above the typical prosecution threshold, comfortably within the course eligibility window, and well below the Band B court level.

Whether enforcement proceeds at all depends on the force, the location, and the specific camera reading. A camera reading of 36 mph after calibration tolerances are applied may correspond to a genuine speed slightly higher or lower. In most parts of England and Wales, 36 mph in a 30 zone is unlikely to result in a fixed penalty or court — but it is not impossible, and it is certainly an offence in law.

💡 If you receive a NIP for a speed in the 35–42 mph range and you are eligible for a course — take it. No points, no licence endorsement, no court. See our full guide to speed awareness courses for what to expect.

Frequently asked questions

At 36 mph you are within the typical speed awareness course window (35–42 mph in a 30 zone). If a NIP is issued, the most likely outcome is a course offer — no fine through the courts, no points. You would only receive a fixed penalty (£100 + 3 points) if you are not eligible for a course due to attending one in the previous 3 years.
At 35 mph you are at the typical prosecution threshold. If action is taken, the most likely offer is a speed awareness course — no points. A fixed penalty with 3 points would only follow if you are ineligible for a course or at speeds above the course window. The threshold is discretionary, not a legal right.
40 mph is within the typical course window. If eligible, you would be offered a speed awareness course — no points, fee of around £80–£100. If you attended a course in the last 3 years you would receive a fixed penalty notice instead: £100 and 3 penalty points.
45 mph is Band B — above the course window. The likely outcome is a court summons. Band B carries a fine of 75–125% of weekly net income, 4–6 penalty points, or a 7–28 day driving ban. Magistrates consider your record and any mitigating factors.
50 mph in a 30 zone is Band C — 20 mph above the limit. This is a court matter. The starting fine is 150% of weekly net income, with 6 penalty points or a 7–56 day disqualification. The actual sentence depends on aggravating factors and your record.
Yes — legally, any speed above the limit is an offence. At 34 mph you are below the typical NPCC prosecution threshold of 35 mph, so most forces in England and Wales would not take action. However this is not a legal right. Police Scotland applies zero tolerance.
