The phrase "road surface changes" refers to any alterations or modifications made to the physical characteristics, texture, or condition of a road's surface. This can include anything from routine maintenance such as paving, resurfacing, or repairs, to more significant changes like adding new markings, adjusting slope or grade, or implementing traffic calming measures. These changes are typically made with the intention of improving safety, reducing wear and tear on vehicles, enhancing driving conditions during adverse weather events, or accommodating other road users such as cyclists or pedestrians.
