We're pleased to hear that you have enjoyed using the Dft Know Your Traffic Signs app! Best wishes, TSO ### 2/5 — Disappointing *2025-10-14* Bear in mind that it doesn’t test your knowledge of ALL road signs and markings, just a minor selection of them. If there’s signs or road markings you have trouble with this may not help you. The practice section asks questions not really related to road signs, but car/bus/lorry driving theory, which for many users will be irrelevant. Kind of false advertising. Waste of money: I wanted to get the knowledge from the og source and got less than I’d find for free on the internet. **Developer response:** Thank you for your review. We add all customer feedback to our development change log and review it as part of our update programme. If you’d like to give us any more information about your experience, please contact us on feedback@williamslea.com, we’d love to hear from you. Many thanks, TSO ### 3/5 — DfT Traffic Signs *2024-10-05* Very useful app to have in your pocket. This app is targeted at new drivers, both car and motorcycle. This is aimed at getting you through your theory test as well as being able to recognise road signs when driving. They have missed several audiences when it comes to the ‘self assessment’ through the practice and tests. For more advanced driving, the test and practice modes are limited in their breadth (150 questions) and recycle the same limited amount of options over and over. Those who are taking further driver training, whether that be HGV, PSV require a more thorough knowledge of both the Highway Code and Traffic Signs, as the pass mark for your theory is higher. Those partaking in Advanced Driver Training either as a DVSA Driving Instructor or anyone working with the road safety charities IAM or RoSPA, who almost need to be able to recite the rules and regulations verbatim, will find the testing here, is insufficient for their needs. I mean, who doesn’t need a better knowledge of how to drive and the driving environment?? **Developer response:** Thanks for taking the time to leave a review. We add all customer feedback to our development change log and review it as part of our update programme. If you’d like to give us any more information about your experience, please contact us on feedback@williamslea.com, we’d love to hear from you. Many thanks, TSO ### 4/5 — Works great but will occasionally freeze. *2024-09-03* I think it freezes on pages with more pictures than text? Usually after a few minutes it will unfreeze **Developer response:** Thank you for your review. Your experience using our app is important to us. Please could I encourage you to contact our technical team via feedback@williamslea.com, who should be able to assist you further.

We are pleased you found the app helpful to prepare for your test. Congratulations on passing your test. Best wishes, TSO ### 5/5 — Recommended for all road users ! *2024-06-04* An excellent app, everything is very well laid out. The quizzes are great, you can easily configure them to suit, they even have separate practice and test modes. You’re given the results straight away and can even go back and review your answers at the end. An invaluable aid to brushing up on your knowledge, whether a learner or experienced driver or rider. **Developer response:** Thank you for your 5 star review! We're glad to hear that you have found our app useful and have enjoyed using it! Best wishes, TSO ### 5/5 — Excellent *2024-06-01* Well organised with modern user interface. **Developer response:** Thank you for your review!
