A European Union plan to introduce MOT-style testing for caravans weighing more than 750kg is being resisted by the Government (BBC News).
The measure would affect many of the estimated 510,000 caravans currently in use in the UK, with only the smallest two-berth models excluded.
The Caravan Club, which represents 375,000 families across the UK, says that its members often have young children and are highly likely to regularly service their caravans for safety reasons.
No price has been set for the test but the Caravan Club has said the cost of establishing it would be huge, with caravan and trailer owners bearing much of the cost.
The Government last year estimated that it would cost £239m to introduce a caravan and trailer registration scheme for the UK, according to BBC News.
A Caravan Club spokeswoman said: "The club will always support practical and effective measures aimed at improving road safety.
"In this case, however, we believe the proposals are not supported by clear evidence that they will address a genuine concern, nor that the practical and economic challenges of implementing them have been sufficiently considered.
"It is therefore likely that the proposals would not deliver a desirable benefit to cost return against any of those criteria and instead could prove a strong disincentive to participate in caravanning, with consequent harm to the entire caravanning sector plus the associated tourism activities."
A Department for Transport spokesman said the move also faced opposition in a number of other European Union countries.
He said: "Member states have already agreed that they do not want to introduce roadworthiness testing for caravans – this includes the UK government and we will continue to resist it."
The roadworthiness regulations are due to be debated by the European Parliament this autumn.
The plan passed their first stage in the parliament last month, despite British MPs speaking out against the idea.
