Question 1

How does Roadworthy calculate trip fuel costs?

Accepted Answer

The planner calculates driving distance and travel time, applies your car's realistic miles-per-gallon (MPG), and uses live petrol and diesel prices along your route to estimate your total fuel spend.

Question 2

Why does Roadworthy check fuel prices along the route corridor?

Accepted Answer

Motorway service stations often charge higher prices than local supermarkets. By checking prices at your starting point, motorway rest stops, and destination, we give you a more accurate forecast of your actual refuelling costs.

Question 3

How does the petrol vs. electric cost comparison work?

Accepted Answer

We compare your vehicle's fuel cost per mile directly against typical electric vehicle charging costs (both home overnight charging and public rapid chargers) so you can see potential savings side by side.

Question 4

Can I adjust my car's MPG or fuel price?

Accepted Answer

Yes. You can fine-tune your vehicle's average MPG, customize petrol or diesel prices, and specify passenger loads to get the most accurate cost estimate for your journey.

Question 5

Does the route show Clean Air Zones or London ULEZ fees?

Accepted Answer

Yes. Once a route is calculated, we test its exact coordinates against official Clean Air Zone and London ULEZ boundaries and show every zone the journey crosses, whether your vehicle is exempt, and the daily charge a non-compliant car would pay. Swap to a different saved vehicle to instantly compare which one is the cheapest drive through the same route.

Question 6

Does the Journey Planner show live traffic and delays?

Accepted Answer

Yes. We show your live arrival time from TomTom alongside free-flow time, any hold-up in minutes, and how many incidents are on your corridor. If you’ve saved the route as a daily commute, we predict traffic for your next departure time instead of just right now, and list each jam, accident or roadworks with where it is, how long the queue is and when it was last reported.

Question 7

How do daily commute alerts work?

Accepted Answer

Save any route as a Journey, pick the days and the time you normally leave, and choose push or email. We check live traffic for that departure and send one daily status overview 15 minutes before you go — with bold ETA and a badge like Standard Traffic, No Incidents or 5 min delay · 1 incident(s). Manage or pause alerts anytime in Profile → Journeys.

Question 8

Can I save a route from the planner for later?

Accepted Answer

Yes. After you calculate a route, tap Save to Journeys. We carry your exact start and destination over to Profile → Journeys pre-filled, so you just pick an alert time and days. Your saved journeys also appear in a picker at the top of the planner to reload instantly.
