Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a literal word-for-word translation like 'кабина сверху'. It is a technical term. Use 'грузовик с кабиной над двигателем' or the loaned term 'кэбовер' in very specific contexts.
- Do not confuse with 'кабриолет' (convertible).
Common Mistakes
- Writing as one word 'cabover' (standard is hyphenated).
- Using it as a verb (e.g., 'to cab-over').
- Confusing it with types of car cabs (e.g., taxi).

FAQ
Frequently Asked Questions
No. A 'semi-truck' (or 'articulated lorry') refers to a truck with a detachable trailer. A 'cab-over' is a design for the tractor unit of such a truck. A semi-truck can have either a cab-over or a conventional (long-nose) design.
Changes in length regulations in the 1980s no longer penalised longer conventional trucks. Conventional designs often offer more comfort (space, ride quality) and easier engine access, leading to their dominance in the long-haul US market.
Technically, many vans and box trucks have a cab-over-engine layout. However, the term 'cab-over' is most strongly associated with heavy-duty tractor units. For vans, terms like 'forward control' or simply 'front-engine van' are more typical.
You do not pronounce the hyphen. Say 'cab' followed by a slight pause or glide, then 'over'. In rapid speech, it flows as a compound: 'cab-over'.
