The main Trans-Canada Highway is uniformly designated as Highway&nbsp;1 across the four western provinces. The British Columbia section of Highway&nbsp;1 is {{cvt|1,045|km}} long, beginning in [[Victoria, British Columbia|Victoria]] at the intersection of [[Douglas Street (Victoria, British Columbia)|Douglas Street]] and Dallas Road (where the "Mile&nbsp;0" plaque stands), and ending on the Alberta border at [[Kicking Horse Pass]]. The highway starts by passing northward along the east coast of [[Vancouver Island]] for {{cvt|99|km}} to [[Nanaimo]] along a mostly-four-lane, heavily-signalized highway. After passing through downtown Nanaimo on a small [[arterial road]], it enters the [[Departure Bay|Departure Bay Terminal]] and crosses the [[Strait of Georgia]] to [[Horseshoe Bay, West Vancouver|Horseshoe Bay]] via [[BC Ferries]]. From there, it travels through [[Metro Vancouver Regional District|Metro Vancouver]] on a four-to-eight-lane freeway before leaving the city and continuing as a four-lane freeway eastward up the [[Fraser Valley]] to [[Hope, British Columbia|Hope]]. There, the Trans-Canada Highway exits the freeway and turns north for {{cvt|186|km}} through [[Fraser Canyon]] and [[Thompson Canyon]] toward [[Cache Creek (British Columbia)|Cache Creek]], mostly as a two-lane rural highway with only occasional traffic lights, while the freeway continues on [[British Columbia Highway 5|Highway 5]]. Approaching [[Kamloops]], Highway&nbsp;1 re-enters a short freeway alignment with Highways 5 (and concurrent [[British Columbia Highway 97|97]]), before passing through Kamloops itself as a four-lane signalized highway. From Kamloops, the highway continues east as a mostly-two-lane rural highway through the Interior of British Columbia, with occasional passing lanes. It widens to a signalized four-lane arterial road for short stretches in [[Salmon Arm, British Columbia|Salmon Arm]], [[Revelstoke, British Columbia|Revelstoke]], and [[Golden, British Columbia|Golden]], but has no signal lights on it for most of its length. The highway crosses two high passes along its route: [[Rogers Pass (British Columbia)|Rogers Pass]] in [[Glacier National Park (Canada)|Glacier National Park]], and [[Kicking Horse Pass]] in [[Yoho National Park]]. At Kicking Horse Pass, the highest point on the whole Trans-Canada Highway system is reached, at {{cvt|1627|m}}.

Speed limits on the Mainland segment of the Trans-Canada Highway in British Columbia range from {{convert|90-100|km/h|abbr=on|mi/h}}, although in towns it can be as low as {{convert|50|km/h|abbr=on|mi/h}}. A combination of difficult terrain and growing urbanization limits posted speeds on the Vancouver Island section to {{cvt|50|kph}} in urban areas, {{convert|80|km/h|abbr=on}} over the [[Malahat, British Columbia|Malahat]] and through suburban areas, and a maximum of {{convert|90|km/h|abbr=on}} in rural areas.
