Classification refers to the allocation of numbers to British roads. There are three tiers of classification: motorways, A-roads and B-roads. Motorways are grade-separated expressways and have 1, 2 or 3-digit numbers prefixed with 'M' or suffixed '(M)'. A-roads are the other major routes; they vary from motorway-standard to narrow local roads, and have 1, 2, 3 or 4-digit numbers prefixed with 'A'. B-roads are local routes and have 3 or 4-digit numbers prefixed with 'B'.

If it is a state route or highway, the letter would distinguish that. M86 could be Michigan (or some other state if located there) Route 86. The capital "i" is for Interstate Freeway. CR before a number indicates County Route.
