Fleet Compliance Checklist

A practical guide for reducing CAZ & ULEZ exposure across Yorkshire and the M62 corridor

ULEZ & CAZ Guide

1. Vehicle Compliance Check

Identify which vehicles are most at risk.

- List all vans, HGVs, and commercial vehicles with Euro rating 

- Highlight Euro 5 diesel vehicles still in operation 

- Check vehicles against Bradford and Sheffield CAZ rules 

- Flag vehicles that entered a CAZ zone in the last 90 days 

- Identify vehicles with repeat PCNs or daily charges 

Outcome: Clear view of which vehicles are driving your cost.

2. Route Exposure Review

Understand where charges are coming from.

- Map regular routes through Bradfords Class C CAZ 

- Check if routes pass through Sheffields inner ring road 

- Review driver deviations that may trigger unexpected charges 

- Identify deliveries that could be retimed or rerouted 

- Check for crosscity routes touching Manchesters ULEZ 

Outcome: Pinpoint the routes that create predictable monthly charges.

3. Cost Impact Snapshot

Estimate your annual exposure.

- Total CAZ charges in the last 12 months

- Total PCNs issued (and repeat offenders)

- Average monthly cost per depot or route

- Highestcost vehicles (top 510)

- Projected cost if no changes are made

Outcome: A simple, honest picture of the financial impact.


4. Operational Adjustments

Quick wins that don’t require major investment.

- Reroute highfrequency trips around Sheffield CAZ 

- Consolidate deliveries to reduce CAZ entries 

- Introduce a preroute compliance check for drivers 

- Add CAZ alerts to routeplanning tools 

- Review idling hotspots and congestion patterns 

Outcome: Immediate reductions in exposure without replacing vehicles.

5. Replacement & Upgrade Planning

Plan upgrades without overspending.

- Identify the 36 vehicles causing most of the cost 

- Prioritise replacements based on CAZ impact, not age alone 

- Consider electric for fixed urban routes 

- Review MercedesBenz Euro 6 and electric options 

- Align replacements with your 612 month planning cycle 

Outcome: A phased, costefficient transition strategy.

6. Compliance Process & Reporting

Keep control of exposure longterm.

- Monthly CAZ/ULEZ cost report

- PCN review and rootcause tracking

- Driver briefing on CAZ zones and rules

- Annual compliance audit

- Clear ownership: who monitors CAZ exposure?

Outcome: No surprises, no hidden costs, no repeat penalties.
