The Difference Between 12AB and 12D: What Job Seekers (and Employers) Need to Know

In traffic management, the tickets you hold determine the kind of work you can do – and the pay rates you can expect. Two of the most common qualifications are Lantra 12AB and Lantra 12D, but many job seekers (and even some employers) aren’t always clear on the difference.

Here’s a simple breakdown of what they mean, who needs them, and what kind of roles they unlock.

What is Lantra 12AB?

The 12AB qualification is for those working on high-speed dual carriageways and motorways, think the M6, M25, or A-road jobs with 50+ mph zones. These are complex, high-risk environments requiring precise setups, rolling roadblocks, and sometimes night work.

12AB roles include:

• Cone laying and removal on high-speed roads

• Working in Impact Protection Vehicles (IPVs)

• Supervising closures and diversions

• Running mobile lane closures

Who needs it? Operatives working for national firms like Chevron, HTM or HBS on motorway contracts will need this as a base qualification. It’s typically combined with IPV and TSCO add-ons.

What is Lantra 12D?

12D is the urban and rural road network equivalent: covering roads under 50mph, such as local authorities, residential areas, and smaller civils sites.

12D roles include:

• Stop/Go or temporary traffic light setups

• Short-term lane closures on town roads

• Footway or verge works

• Local authority and civils contracts

Who needs it? Operatives working in towns, cities, and rural roads with civils firms or utilities contractors will almost always be 12D trained. It’s often a first step into the industry.

Which one should you get?

If you’re just starting out, 12D is more accessible and widely used. But if you’re aiming to work on motorways or progress into more specialist roles, 12AB (plus IPV) is a must.

For Employers

Understanding the difference helps you post the right job, get better applicants, and set accurate pay rates. Want motorway-experienced staff? Ask for 12AB/IPV. Need town road crews? 12D will cover it.
