It is easy to let a date drift, believing the cost is only a modest fine. The quieter truth is that a lapsed inspection can reach into your insurance, precisely when you would rather it did not.
A penalty is the visible cost. Less visible is the effect on your insurance, where cover can be complicated or compromised if the vehicle was not road-legal at the moment it mattered most.
There is inconvenience too: a car flagged as overdue invites scrutiny, and resolving it under time pressure is always harder than handling it calmly on your own schedule.
Seen plainly, the roadworthiness test is less a hurdle placed in your way than a small, regular policy on your own peace of mind.
