A limousine business in Dubai is a high-demand, profitable venture due to robust tourism and a wealthy clientele, requiring RTA approval, a valid trade license (Limousine Transport activity), and significant investment (AED 100k-1M+ for setup/vehicles), with operations needing professional drivers, RTA-compliant vehicles (often new models), a physical office, and adherence to specific regulations for booking, vehicle maintenance, and service quality to cater to luxury hotels, events, and corporate clients.
