The problem
Rules for hauliers change and vary by place: a clean air zone in a city on a new contract, drivers' hours for a job that crosses into Europe, a council's lorry restrictions. If the transport manager spends 4 hours a month digging through pages and forums before quoting or planning these jobs, that's time away from planning, and an out-of-date answer can mean an unexpected charge or an infringement.
What the AI does
Perplexity answers with inline citations on every plan, the free one included. The transport manager asks a specific question, such as whether an older lorry pays to enter a named city's clean air zone or which drivers' hours rules apply to a job into France, and asks for GOV.UK, DVSA and council sources. The manager opens each source, reads the current guidance and keeps the link with the job file. Where the answer decides the job, the official page is followed, not the summary.
A worked example
A haulier in Stoke-on-Trent with 9 lorries is quoting regular runs into new cities and the occasional job into France. The transport manager uses Perplexity's free plan for the rules questions before quoting.
Before
About 4 hours a month searching for rules before quoting and planning
After
About 1.5 hours, including reading the official pages linked

How to set it up
- Create a free Perplexity account; cited answers are on every plan.
- Ask one specific question at a time, naming the city or country, the vehicle type and the route, and ask for GOV.UK, DVSA or council sources.
- Open each source and check its date and that it covers your vehicle and journey.
- Build any charges into the quote and keep the link and the date checked on the job file.
- For drivers' hours on unfamiliar journeys, confirm the rules with DVSA guidance or your tachograph analysis provider before planning the job.
What goes wrong
- Rules for GB, Northern Ireland and EU journeys differ, and an answer can mix them. Check the source covers the journey.
- Clean air zone charges and boundaries change. Check the council's own page the week you quote.
- A cited summary isn't compliance. The transport manager stays responsible under the operator's license.
- The free plan limits Deep Research; everyday cited answers are on every plan.
