If the drive serves outbuildings as well as the house, specify the heaviest expected vehicle and all access routes.
Why it matters for your tarmac surfacing: Record the narrowest route, gate openings, storage space and any restrictions on delivery or unloading. For tarmac surfacing, it can affect excavation, compaction, course depths, drainage, edge support and the handover programme.
