German retail association pushes for permanent use of longer trucks to mitigate low-water transport disruptions on rivers
Executive summary: The German Retail Federation (HDE) warned of supply bottlenecks due to extreme low water levels on rivers and called for longer trucks to be deployed in regular operations to offset reduced barge capacity. Recurring low water levels disrupt inland shipping, a critical freight corridor for German industry, increasing logistics costs and risking just-in-time deliveries; shifting to road via longer trucks offers a short-term adaptation but shifts environmental and infrastructural burdens.
Who is involved: HDE (German Retail Federation), German federal and state transport authorities, logistics companies, rail and barge operators, environmental agencies.
Likely next: Pilot programs for Lang-Lkw on key corridors may be extended; federal ministries will assess infrastructure impacts and emissions; debate over permanent regulatory changes will intensify if low-water events persist.
The German Retail Federation (HDE) is advocating for the regular deployment of longer trucks (Lang-Lkw) to compensate for reduced river barge capacity caused by persistently low water levels on major German rivers. This follows a temporary suspension of truck bans on certain routes to shift freight from water to road. The proposal aims to maintain supply chain resilience amid recurring climate-driven navigation constraints, though it raises questions about road congestion, infrastructure wear, and emissions trade-offs.
What's next — scenarios
Permanent Regulatory Shift (50%)
Logistics providers increase capital expenditure in long-combination vehicles to capture long-term river-bypass contracts.
- Federal Ministry of Transport issues new guidelines for Lang-Lkw deployment
- Abolishment of temporary truck ban exemptions on key corridors
Infrastructure Deadlock (30%)
Retail margins are squeezed by rising road freight costs as road congestion and toll increases offset barge savings.
- Local municipality petitions to block Lang-Lkw routes due to weight limits
- Increase in road maintenance levies for heavy freight
Climate-Driven Barge Resilience (20%)
Investment in long-trucks is delayed as water levels stabilize, maintaining low-cost water transport dominance.
- Normal seasonal precipitation levels in Rhine/Danube basins
- Barge capacity rates returning to pre-drought levels
What to watch
- German Federal Ministry of Transport policy announcements (next 60 days)
- Rhine water level forecasts for the upcoming summer season (next 90 days)
- HDE quarterly lobby activity reports (next 30 days)
- Freight rate volatility between road and water transport (next 60 days)

Analysis — what this means
Likely next events
- Federal Ministry of Transport to evaluate Lang-Lkw trial results by Q4 2026
- HDE to present cost-benefit analysis of modal shift to Bundestag transport committee in September 2026
- Next major low-water alert expected on Rhine if September rainfall remains below average
Sectors affected
- Inland shipping
- Road freight logistics
- Retail supply chains
- Heavy truck manufacturing
Regulatory implications
- Potential amendment to German road traffic regulations (StVO) to permit permanent Lang-Lkw use on federal highways
- EU-level review needed if longer trucks exceed current cross-border weight and length directives
