Research conducted by the RAC indicates that overgrown foliage along roadways frequently obscures speed‑limit signs, and this visual blockage leads almost one‑fifth of motorists to exceed the legal speed limit without realizing they are doing so.
Drivers report hidden speed limits
A recent poll asked drivers about their experiences with concealed traffic signs. Nineteen percent of respondents admitted that they had broken the speed limit because a speed‑limit sign was hidden behind dense trees or hedges, a situation they described as both frustrating and unsafe.
Almost every participant—ninety‑four percent—reported having seen at least one road sign covered by branches, trees, or hedges during their daily commutes or occasional trips, confirming that the problem is widespread across many regions.
More than half of those surveyed, fifty‑one percent, stated that they encounter such obstructions on a regular basis, indicating that the issue is not limited to isolated incidents but forms a recurring challenge for drivers.
The most frequently concealed markers were speed‑limit signs, stop signs, and give‑way signs, according to the same questionnaire, showing that critical regulatory information is often the most affected.
As a direct result, twenty‑one percent of drivers missed a turn, thirteen percent had to brake sharply to avoid a collision, and five percent ignored a give‑way sign entirely, each scenario increasing the likelihood of near‑misses or accidents.

Four‑fifths of motorists said that excessive vegetation made it hard to pull out of a junction or roundabout safely, highlighting how overgrown plants can impair both visibility and maneuverability.
Hidden signs create danger.
Legal responsibilities for property owners
The RAC warns homeowners that failing to prune plants that overhang public roads can trigger legal action from local authorities.
Local councils may issue a notice under Section 154 of the Highways Act 1980 requiring removal of the obstruction within fourteen days, a timeframe designed to prompt swift remedial work.
If the owner does not act within that period, the authority can carry out the necessary trimming itself and then bill the resident for the cost, shifting the financial burden to the property holder.
Willful obstruction of a highway is punishable under Section 137 of the Highways Act, carrying a potential fine of up to £1,000 or up to fifty‑one weeks’ imprisonment, a penalty structure intended to deter deliberate neglect.
Harriet Hernando of the organisation added, “As many welcome rain to give their gardens a much‑needed boost after such a dry summer, it’s worth checking whether any plants, branches or hedges growing on your property spill onto a public road or pavement.”

She continued, “Cutting them back to ensure signs are clearly visible, and pavements are free from any obstacles, goes a long way in ensuring the roads are safe for all.”
Drivers can report obscured signs to the local council, or to National Highways if the problem occurs on a motorway or major trunk road, providing a clear channel for community‑level intervention.
Safety implications and next steps
Beyond speed‑limit breaches, eighty percent of respondents struggled to exit junctions safely because vegetation‑blocked sightlines limited their ability to see oncoming traffic, a factor that directly compromises junction safety.
Missing a give‑way sign, though less common, can have catastrophic consequences, especially at busy intersections where multiple streams of traffic converge and the margin for error is slim.
Local authorities are encouraged to enforce pruning standards, and residents are urged to act before a notice is issued, creating a proactive approach that reduces the need for enforcement after the fact.
In practice, a homeowner who trims back hedges promptly avoids both a potential fine and the safety hazards that stem from hidden traffic markers, turning a simple gardening task into a public‑safety measure.
